Zero Tolerance 0350 Review

Last Updated: April 5, 2020

My Zero Tolerance 0300 got a lot of looks when I carried it around. At over 9″ long and with a weight of 8.6 ounces, it definitely raised some eyebrows. The excellent S30V blade was a force to be reckoned with, and I really enjoyed the loud “thwack” of the assisted opening. It was generally a really cool knife to carry, but lets be real, it’s not always practical to tote around such a beast of a blade every day. After a while a knife of that size (and weight!) might get pushed to the back of your EDC rotation, to eventually fall off into a dark corner of your knife collection.

So the good folks over at Zero Tolerance decided to tone things down a little and offer a slightly tamer, yet no less cool version of the original 0300; the Zero Tolerance 0350. This little brother packs many of the great features that made me fall in love with the 0300, but comes in a size that is much more practical for many people to EDC (although it’s still a big knife – lets not kid ourselves). Lets take a closer look and see what the ZT 0350 is all about.

General Dimensions and Blade Details

WHile the 0350 is not as portly as it’s big brother, it still is not what I would call a “small knife.” The 0350 has an overall length of 7-5/8″ a 3-1/4″ blade and a weight of 6.2 ounces. So it’s still on the heavy side, and perhaps still too big for some to EDC, but if a sturdy good size folder is what you are after I don’t think it’s a huge issue.

The blade is a modified drop point design. There is a small recurve and tons of belly. This is the same blade shape found on the 0300, just shrunk down slightly. I like how the tip has been left very strong. The tip of the 0350 has good piercing strength, and the high flat grind makes the knife excellent for slicing. While recurves can be a pain to sharpen, they really help feed material into the edge and are great slicers. ZT rounded things off by applying a beautiful edge and laser engraved hallmarks. This is a great blade shape a wide variety of applications.

The steel on this knife is S30V, which is absolutely awesome stuff. I am a big fan of S30V because it holds a very nice edge for a long time, and is still reasonably easy to sharpen. S30V is also resistant to rust and corrosion. Zero Tolerance applied a very nice DLC (diamond like carbon) coating to the knife, which is about as durable as knife coatings get. In summary, this is a great blade shape made of great steel with a great coating applied to it.

Handle, Ergonomics, and Pocket Clip

The ZT 0350 features a classic handle formulation – black G10 over very thick stainless steel liners. The handle has been meticulously finished – I absolutely love how everything lines up perfectly, and there isn’t a machining mark to be seen. As far as construction goes, everything is held together with torx bolts, and you have a partial G10 backspacer. My only suggestion for Zero Tolerance would be to mill out the liners a little to perhaps shave off a few tenths of an ounce. Really though, this handle is built like a tank and finished like a Swiss watch.

The ergonomics on the 0350 are extremely satisfying. I wear a large glove and it feels like the knife was custom made for my hand. The width and thickness to the handle really fills the palm while the choil and thumb ramp prevent your fingers from slipping forward. The G10 has a medium level of traction, which is very pleasant feeling and offers good feedback. In reverse grip there is additional jimping for your thumb. All in all it’s a very comfortable and secure grip.

The pocket clip is right out of the Kershaw parts bin and is simple, but effective. First of all, it’s unobtrusive with it’s flat black coating. It has excellent retention, which I find extremely important for a heavier knife – this means that the knife won’t slide around your pocket (or worse, fall out entirely). The fact that this is a true 4 corners clip (ambidextrous tip up or tip down carry) almost brings a tear to my eye. This is truly a well done pocket clip.

Actual carry isn’t that bad. I found the knife is about as unobtrusive as 6+ ounces can get, although it’s certainly a change from say, my more typical 3-4 ounce EDC knives. For guys who regularly carry larger knives, I don’t anticipate any problems at all.

Deployment and Lockup

The ZT 0350 gives you the option of either a flipper or thumb studs for deployment. In practice, only the right hand thumb stud is available (the left side sits too close to the handles) but my preference is for the flipper anyways. Either way the knife springs to life with very little effort due to the stellar Speedsafe assisted opening mechanism and high quality phosphor bronze washers. This is a knife that fires hard and fires fast. And on a tactical knife, this kind of easy of deployment can be the difference between life and death. If assisted opening knives aren’t your thing, it’s easy enough to remove the spring – deployment will be smooth regardless.

Lockup on the 0350 is accomplished by a very beefy liner lock. This is a very well executed liner lock, and it bites in early with plenty of room for wear. One of the biggest differences between the 0350 and the 0300 is the absence of the titanium framelock, but I have just as much confidence in this very thick liner. It almost goes without saying, but I didn’t detect blade play in any direction.

Zero Tolerance 0300 or Zero Tolerance 0350?

A common question people have is whether they want the ZT 0350 or the larger ZT 0300. If you are one of those people, I made a video comparing the two knives.

Zero Tolerance 0350 Review – Final Thoughts

The Zero Tolerance 0350 is an absolutely outstanding knife. I love everything about it, from the choice of materials, to the incredible fit and finish, to the stellar design, to the great ergonomics, right on down to the excellent pocket clip. I am also very pleased to see that this knife is made in America and still comes in at a decent price.

Currently these can be had for right around $100. When you consider how well this knife is made, I think it represents an excellent value – especially when the 0300 costs over $200. It’s been a real pleasure having this knife in my collection and it really makes me excited to review more Zero Tolerance knives in the future. The company really seems to know how to put together a great blade and am truly excited to see what they have coming up next.

Spyderco Sage 1 Review

by Dan Jackson 24 Comments

Last Updated: July 20, 2019
A while back I took a look at the Spyderco Sage 2. The Sage 2 is an absolutely fantastic knife and with it’s eye catching titanium handle, I find that the Sage 1 often plays second fiddle.

Buy the Sage 1 at BladeHQ

Buy on Amazon

That is a shame, because I think that the Sage 1 may be the better EDC knife – at least for me. Regardless, I can safely say that it’s an excellent EDC knife.

Clearly, it’s high time I reviewed my Sage 1. Let’s take a closer look and see why I like this knife so much.

Purpose

The Sage 1 is arguably the perfect EDC knife for my purposes. Yes, you read that right. The Sage 1 is my personal EDC blade, and for my purposes I couldn’t ask for a better knife. What I like about the Sage 1 is that it has perfect EDC proportions, excellent materials, outstanding fit and finish and it carries very well.

In addition to EDC, I think this knife is a great collector’s piece (I know plenty of people who have all 3 of the knives in the Sage series) and while the Sage 1 is not billed as a tactical knife, it could certainly fulfill an emergency tactical role. Finally, the carbon fiber and stealthy carry make this a great option for a gentleman’s folder.

General Dimensions and Blade Details

As for the dimensions we have a 3″ blade, an overall length of 7 1/8″ and a weight of 3.2 ounces. Going back to me calling the Sage 1 the “perfect” EDC knife, the dimensions of the Sage 1 are ideal for EDC in my book. I really don’t like carrying anything smaller, and anything bigger starts to raise some eyebrows (sad, but true). The Sage 2 actually handles like a bigger knife, but it remains small and is people friendly.

The blade is a classic Spyderco leaf shape given a nice full flat grind. There is a decent amount of belly and the tip has a sturdy point while still being strong. This is a very practical blade shape that is also non-threatening to people who don’t understand knives.

The blade steel is S30V which was a gold standard for production knives for many years. When I originally wrote this review in 2011, it was about as good as you would find in any $100 knife. It’s still a great choice, but I would not complaint if they upgraded to S35VN, or chose CTS-XHP like on the Chaparral. S30V is a harder steel, so sharpening takes more effort than say, AUS8 and other more inexpensive steels. However, S30V it takes a good edge and holds it well. S30V is also very resistant to rust and corrosion. Given the price point and intended use of the knife I think this is a great steel.

Handle, Ergonomics and Pocket Clip

The handle is part of what sets each Sage apart, and the Sage 1 has carbon fiber scales over stainless steel liners. The carbon fiber is left with a “woven” or “twill” texture that provides some traction and is pleasant in hand. The entire knife is held together by 3 hex bolts, and the flow through design is an exercise in restraint. Looking inside you can see that the liners have been milled out extensively. I count no less than 4 different size bits used to mill this liner out. Everything has been expertly finished and polished up – including the liners.

The ergonomics are another huge plus to the Sage 1 (and the entire Sage series really). First of all, there is a nice 50/50 choil and a large thumb ramp. This makes the most of the relatively small handle and provides plenty of room, even for larger hands, in practically any grip. I absolutely love the ergonomics of the Sage, it’s much like the Caly 3 if you have ever handled one of them. Basically it gives you a big knife grip in a small easy to carry package.

The pocket clip is another home run. While pocket clips are often a source of grief for me the Sage 1’s clip is about to close to perfect as I can ask for. The Sages all use the Spyderco “wire” clip, which is actually a very strong piece of tempered steel. What sets the Sage 1 apart is that has given the clip a black coating. Not only has the coating held up extremely well, the knife disappears when you clip it to the pocket. If you work in an office, this is the perfect knife – it’s very difficult to notice this knife when wearing slacks (ultimate urban camo). Finally, I have to mention that Spyderco gives you the option for ambidextrous tip up carry. This is perfect for my applications.

Lock and Deployment

The Sage 1 uses a liner lock, and not just any liner lock but a “Walker Linerlock.” That is because the Sage series was designed to pay homage to innovators in the knife industry and the Sage 1 was made to honor Michael Walker. Michael Walker is known for designing the ball-bearing detent method of holding a lock in place which is used in many many knives today. A knife designed around a lock should have decent lockup, and the Sage 1 does not disappoint. The lock makes a very crisp “click” when engaged and it bites in nice and early. There is absolutely zero play in any direction. This is a very strong liner lock worthy of paying homage to Michael Walker.

Deployment is accomplished by a 1/2″ Spyderhole. I found deployment to initially be pretty stiff on the Sage 1. For a while this was my only real complaint with the knife. However, it took a while but the knife slowly broke in. These days deployment is very smooth and it only seems to be getting smoother (after months of carry). Of course there are some large phosphor bronze washers in there which reduces the friction but the tolerances are very tight on this knife – in my experience this knife will take time to break in but is well worth the wait.

Spyderco Sage 1 vs. Spyderco Caly 3 Carbon Fiber

Ah, the age old question. Two beautiful Spyderco knives that are very similar in size, price and materials yet have some interesting differences as well. Which one should you choose? Well, I attempted to answer that question with a youtube video. It’s not an easy answer, but I like the idea of saying “the Sage 1 is my wife and the Caly 3 is my mistress.” Really that Caly 3 is built like nothing else, just an awesome knife that has the “soul” I think the Sage 1 lacks in some way (difficult to describe). That said, for all out practical EDC use, I prefer the Sage 1. The knife rocks, it’s designed to be used and will be up for any challenge. Buy ’em both if you have the money, I don’t think you will be disappointed with either one.

Spyderco Sage 1 Review – Final Thoughts

So yeah, what is there left to say? Not a whole lot really, the Sage 1 is just a fantastic knife. I stand by my original comment that this is the “perfect EDC knife” for me – even months after writing the first draft of this review – this one’s a keeper! Sure it all comes down to personal preference, but I’ve handled a lot of knives and if you are looking in the ~3″ blade EDC knife category, it’s going to be hard to find something as well rounded and beautifully executed as the Sage 1.

I tell you, I write very few reviews that are this positive, I literally have nothing bad to say about the Sage 1. The overall fit and finish on this knife is outstanding. Every surface has been polished, the blade centering is dead on, and everything has been done to an almost eerie state of perfection. If you are on the fence about the Sage 1 my advice would be to go ahead and buy it. You will not be disappointed.

Update – I originally wrote this review in 2011. I still have my Sage 1, still carry it, still use it, and still enjoy it. It remains one of my all time favorite EDC pieces. This continues to be an excellent knife.

Spyderco Sage 2 Review

by Dan Jackson 14 Comments

Last Updated: August 2, 2019
Today I am looking at another beautiful knife, the Spyderco Sage 2. The Sage series is designed to pay homage to various pioneers in the knifemaking industry and to recognize some of the talented custom knifemakers that have helped re-define pocket knives.

Buy the Sage 2 at BladeHQ

Buy on Amazon

The Sage 1 pays homage to knifemaker Michael Walker who invented the liner lock and features carbon fiber scales while the Sage 2 focuses on knifemaker Chris Reeve’s Reeve Integral Lock (or frame lock). For those unfamiliar with Chris Reeve Knives (CRK), his “semi-production” knives are considered to be the holy grail among many knife enthusiasts. They are beautiful pieces and are quite pricey. What appeals to me about the Sage 2 is that you get a lot of what makes the CRK so desirable at a fraction of the cost.

General Dimensions and Blade Details

The Sage 2 has an overall length of 7 1/8″, a 3″ blade, and weighs of 3.5 ounces. These are great numbers in my opinion. The Sage 2 packs a lot into a small and lightweight package. This is an ideal size for every day carry, and the Sage 1 has proven itself to be one of my all time favorite EDC knives. The Sage 2 is just as carryable and makes for a great upscale EDC. The Sage 2 is made in Taichung Taiwan.

The blade is 1/8″ thick which is nice and beefy, it makes for a stout knife which is still light and agile. Spyderco went with their classic leaf shaped blade, with the full flat grind that many people love. The full flat grind is beautiful and makes this knife a great slicer.

Spyderco selected CPM S30V for the blade steel. Back when I first penned this review in 2011, S30V was a high end steel. Today (late 2016), S30V has lost some of its luster next to steels like S35VN, CTS-XHP, and even more exotic steels like M390, but this is still serviceable steel. It’s a little more brittle than I would like, and can be difficult to sharpen at times, but it’s still reasonably easy to sharpen and holds a good edge. It’s a good steel, but admittedly not a great steel. I’d like to see Spyderco update the Sage series to S35VN at some point.

Handle, Ergonomics and Pocket Clip

The handle is where the Sage 2 really shines. It is made of 2 thick slabs of titanium and is held together by 3 torx bolts. I really like the simplicity of the handle. The titanium keeps this knife lightweight and is nicely finished. The flow through construction and easy disassembly are two other features that I love. They make this an easy knife to clean and maintain.

The ergonomics are also very nice. The handle length is only 4 3/16″ however the jimping on the thumb ramp and choil allow you to choke up real close to the blade. Like most Spyderco knives I have held the Sage 2 feels good in hand and will make an excellent user for someone looking at a high end working knife or EDC item. The handle edges are also well finished with no sharp edges or “hot spots.”

The pocket clip is the Spyderco wire clip. I think that this is a great pocket clip design because it is simple, strong and easy to conceal. Some people do not like the wire clip. I think those people are nuts, but there is plenty of room for multiple opinions.

The retention of the pocket clip is perfect and the deep carry nature of the clip makes the knife almost disappear in pocket. Spyderco designed this knife tip up carry only however the clip is ambidextrous. For me this isn’t a problem although I understand that sometimes people prefer tip down. If that is your desire Spyderco makes plenty of knives with that feature. I tend to prefer blackened clips as it makes them even more discreet, but I can see how that might spoil the aesthetics of the Sage 2.

Deployment and Lock

Deployment on the Sage 2 is a breeze with the standard Spyder-hole and phosphor bronze bushings. The blade moves with very little effort from your thumb and the sound the knife makes when it locks is very fun and satisfying. With the Caly 3 (and other lockback knives) I noticed it takes some effort to flick the blade out but the Sage is practically effortless. That said, retention is still good, it’s not like the blade is falling out of the handle – it’s only once you give it that initial push that you get the incredibly smooth deployment.

Now, the lock is really the first thing I wanted to talk about (since the entire knife is designed to showcase the lock) but I try to keep a method to the madness here and like to do my reviews “in order” so my regular readers know where to find exactly what they are looking for. The Chris Reeve’s designed framelock is a beast and is among the strongest locks you can buy. The lock’s strength lies in its simplicity. The entire titanium handle locks the blade in place.

I am left handed and this is not a left handed knife. That said, this knife is still easy to disengage with my left hand although I would love to see a dedicated lefty version some day.

Spyderco Sage 2 Review – Final Thoughts

The Sage 2 is an excellent knife and a worthy successor to the Sage 1. The materials, fit, and finish are top notch and the design is pure Spyderco. The retail price for the Sage 2 is around $175. I know for some that will be too much money to spend on a knife, but when you compare that to the other titanium frame lock knives on the market (including Hinderer, Strider, and Chris Reeve Knives) the Sage 2 offers a compelling value proposition. Granted, the Sage 2 is made overseas, but Spyderco’s Taiwanese knives are all excellent. There is not a single manufacturing flaw with the knife and I am extremely impressed with the level of fit and finish. I can’t think of another titanium framelock out there that can touch the value and performance of the Spyderco Sage 2 except for perhaps the Boker Urban Trapper.

If you are in the market for a titanium frame lock knife, but aren’t ready to shell out the big bucks for Chris Reeve, or similar offering, then I can absolutely recommend the Spyderco Sage 2. The Sage 2, along with the Sage 1, are some of my all time favorite EDC knives. These are top shelf knives that can both be had for a reasonable amount of money.

Spyderco Military Review

by Dan Jackson 5 Comments

Last updated: February 14, 2019
Those in the military, law enforcement and contract defense firms require high quality gear designed to meet the rigorous demands of these types of positions. The Spyderco Military was designed to meet these demands as either a large utility knife or a full on tactical blade. In addition to law enforcement and military use, this could be an excellent civilian self defense blade or an oversize EDC knife. Lets take a look at what sets this knife apart from Spyderco’s more civilian oriented offerings.

Buy the Spyderco Military at BladeHQ

Buy on Amazon

General Dimensions and Blade Details

The Spyderco Military has an overall length of 9.5″, a 4″ blade, weighs 4.2 ounces, and is made in the USA. It’s a large knife, but when you pick it up I think most will very surprised how light it feels. The knife is extremely light for it size, making it practical for both a hard working tool and as a dedicated self defense knife.

The blade on the Military is a modified drop point design. Spyderco started with 1/8″ blade stock, added a nice full belly, and applied a full flat grind. This is quintessential Spyderco blade, simple, elegant and entirely effective. There is no swedge or recurve – just a simple and utilitarian cutting surface. The tip is unreinforced, and is somewhat delicate if you aren’t careful with it, but I find the blade to overall be very well balanced and good at a variety of cutting tasks.

Spyderco selected CPM-S30V stainless steel for the blade. S30V is excellent stuff. It’s best known for holding a great edge, but it’s also fairly easy to sharpen and very corrosion resistant. I think for a combat knife S30V was a good choice here, provided that you are willing to occasionally sharpen and maintain the edge.

Handle, Ergonomics and Pocket Clip

The Spyderco Military features a large handle, designed for serious use. As far as construction is concerned, Spyderco started out with large pieces of G10 and added nested partial steel liners. This provides a lot of strength and rigidity but is also what keeps this knife at an amazing 4.2 ounces. The steel liners are screwed into an aluminum backspacer. Everything can be taken apart and is extremely easy to clean. This is a simple and very effective handle design.

When discussing the ergonomics of the Military, the first thing to mention is how large this handle actually is. I can almost get a 2 hand grip on it – and I wear large gloves. This gives you plenty of room for forward or reverse grips with or without gloves. The G10 provides plenty of traction and Spyderco has done a great job of jimping the thumb ramp and choil. This is very aggressive jimping and it works very well. There is also a small choil so you can choke up on the blade. I’m a big fan of this choil – it allows the Military to flex between a defensive (or offensive) tool, and a straight up utility knife. The ergonomics on the Military are outstanding.

The clip is a simple affair, it’s been blackened and is made of tempered steel. One of the biggest complaints peole have with this knife is that the clip is tip down right side carry only. I know most people prefer tip up, and that would be my preference as well. However, there are no steel liners near the butt of the handle, so there really is no place to add a clip unless you want to significantly increase the weight by adding a larger liner. For people wanting left side carry, Spyderco has a separate left-hand version of the Military available here.

All in all, the clip is good. It rides decently low, it’s discreet and has good retention. Tip up carry would be nice but it’s not feasible given the overall design.

Deployment and Lockup

The Spyderco Military, utilizes an oversize thumb hole (or a “Spyder hole”) for deployment. Deployment on my knife is pretty fast. The thumb hole is a generous 14mm in diameter, which allows for easy access with bare hands or gloves. I can flick the blade out on my new Military, but it takes a little more force. With time the knife and it’s high quality phosphor bronze washers will break in, and deployment will only get smoother and easier.

After deployment the blade is locked in place with a thick steel liner lock. When the lock engages its sounds sorta like someone stepped into a bear trap – it makes a very crisp and satisfying “SNAP” when it locks in place. Lockup is very secure. There is no blade play at all. The partial liners are bolted together through the aluminum backspacer – this is just a rock solid design and again, I’m blown away by the fact that this knife only weighs 4.2 ounces. To have such a big knife with such a strong lock with this weight puts the Military in a class of its own.

Spyderco Military Review – Final Thoughts

The Spyderco Military is an amazing folding tactical knife. With its light weight, large handle and incredibly versatile blade, the Military is made with tactical use in mind. It’s a very well thought out design, and Spyderco has been refining the knife for years. I also really like how the Military is made in America.

In terms of potential criticisms, I would caution readers on the relatively delicate tip of the blade, and the fact that the pocket clip is designed for tip down carry only. If you want a folder that doubles as a pry-bar, I’d look elsewhere (the Zero Tolerance 0550 comes to mind), but if you want a practical tactical knife you will not be disappointed with a Military.
