Freeman Outdoor Gear 451 Flipper Review

by Benjamin Schwartz 6 Comments

Last Updated: August 5, 2019
Few of us have the money to shell out hundreds of dollars for every knife we think we might like. We have to cull the herd. Maybe we splash out for a promising ‘Maybe’ every once in a while, but 80% of the time we go for the sure thing. Most of the knives I skip I forget about, with nary a second thought given them. But every so often a Maybe knife won’t be forgotten. It lingers in the memory and asks me over and over again, “What if you’re missing out on something special?”

Freeman 451

Such was the case with the Freeman Outdoor Gear 451 Flipper. I heard good things, and admired the flipping action, unique aesthetic, and button lock mechanism from afar. My cursor would hover over the “Add to Cart” button on the Freeman website, but I never could quite commit. Thankfully, a friend and fellow gear geek offered to send his 451 my way to try out.

After wondering for years what this knife is like, I’ve had a chance to try it out, and the news is mostly very good. The Freeman 451 flipper manages to bring a unique set of features to a section of the market that is saturated with a lot of sameness. It goes deeper than a straightforward recommendation, but there’s a lot of interesting things to cover.

General Dimensions and Blade Details

The 451 has a blade length of 3 5/8”, a handle length of 5 1/8”, an overall length of 8 13/16”, and is made in the USA. There are bigger blades than the 451, but this pushes up right against the limit of what I would consider reasonable proportions for something that folds and is meant to be carried the pocket. That is strictly a function of the 451’s overall shape, however: at 5.5 oz. it’s actually quite light for its size.

The market is so rife with drop points that you think I’d be sick of looking at them. However, the proportions and grind make the 451’s blade shape memorable and useful. This feels like a blade that can take a beating , with thick blade stock and a lot of material brought right up behind the edge, but the grind is masterful: a mirror-polished secondary bevel that is nice and wide without being thin or brittle. The result is a combination of toughness and slicing ability that is rare in big blades. This is probably as good a balance as you’re likely to see on a knife this size.

Freeman 451 Blade

The striations on the blade are bound to polarizing. I actually think they’re look pretty good, and they make cutting through choky material like cardboard easier. The knife almost ‘revs up:’ the longer the pull through material, the easier it gets. They might cause issues with long-term sharpening, but other than that I can’t complain.

Steel here is D2. This is a venerable tool steel that I have had very little experience with before now. The edge was very clean and very sharp. I think the thick stock and wide-but-not-narrow edge bevel really accentuate D2’s edge holding ability while minimizing its reported tendency to chip. In another smart move Jeff Freeman chose to Cerakote the blade. As a semi-stainless tool steel, rust is a concern with D2. In an uncoated blade the grooves would give me pause; I can see moisture creeping into them and wreaking havoc. Thankfully, between the coating and the mirror polish on the bare edge, I’d say you’re pretty much protected set barring grossly neglectful behavior.

Handle, Ergonomics, and Carry

The handle on the 451 looks like your average one finger groove affair, but that isn’t quite how it feels when you’re holding it. That finger groove is huge. It can accommodate two fingers, actually, but it works best with one finger in it. Holding the knife naturally, the pointer finger rests at the very bottom of the groove. This gives your knuckle some clearance so it isn’t butting up against the flipper tab – something that so many flipper knives neglect to do.

Freeman 451 Handle

In terms of control, it’s good. Your hand is situated pretty far back. You undoubtedly lose fine control, but fine cutting tasks aren’t the 451’s calling. I used to think that all big knives that couldn’t also do fine cutting were needlessly sacrificing something, but that’s not true. Just because the PM2 can function as an EDC doesn’t mean that all larger knives have to, and really the PM2 is just barely a big a knife anyway. The 451 is much more clearly meant for specific kinds of tasks, and in those tasks the ergonomics are great. There’s a sort of finger choil on the blade itself as well, but I found it a little too close to the edge for my comfort.

Freeman 451 Ergonomics

The 451 carries quite well for a big knife. You could EDC it if you wanted and not be totally displeased with the in-pocket feel. But where I think the 451 excels is in its lightness and narrow frame relative to other hard-use big blades. You aren’t going to feel like you have a paperback strapped to your thigh carrying the 451 on a hike. The aluminum frame is gentle on your pockets and the titanium clip is adequately-tensioned and beefy as hell.

Deployment and Lockup

I don’t think flippers are, in any way, an improvement over thumb studs or opening holes. I tend to think that they are in fact actively worse. They often muck up the ergonomics of a knife, and they always make it a worse carry. The 451 makes its flipper as agreeable as possible.

Freeman 451 closed

It deploys surely and swiftly every time. The weight of the blade and the strength of the detent make the 451 a snappy and sure flipper. You have to try to mess up the flipping in order to get the 451 to not lock up. It’s hard to do.

The button lock is still something of a novelty in the knife world, isn’t it? Hogue has been using it with success, but other than that the only non-automatic production maker using button locks regularly is Gerber. Maybe this is a vestige of Freeman’s influence on the company (he was head designer there for many years), who knows.

Either way, the Freeman clearly believes in the button lock, and it’s easy to see why. On the 451 it is strong, secure, and easy to engage/disengage. Your fingers don’t have to be in the blade channel to disengage it – a major positive given the free-swinging blade. There is variability in the amount of play I get when I lock the 451 up, but it’s never enough play that I care. The button lock also sticks to greater or lesser degrees depending on how hard you flick it. I think these are characteristics of the lock design, and not indicative of poor fit and finish or tolerancing.

Freeman 451 vs. Spyderco Delica

In many ways this button lock reminds me of the Axis Lock. It’s probably slightly worse than the Axis, if only because it isn’t ambidextrous, but I never doubted its strength or security, and I am happy to see something in this price range without a frame lock.

Freeman 451 Flipper Review – Final Thoughts

I’m glad I got to try out the 451 flipper. It answers a question I’ve been asking for a long time: Is it a good knife? The answer is a definite yes. Would I buy one for myself? That’s a tougher call. When the 451 first came out, it was a little cheaper ($200 instead of $225), and the market was way less competitive. If you’re looking for a big high-end knife there are a lot of choices out there at or under the same cost, some with better features like S35VN steel – which you can get on the 451, but for a significant premium that puts the knife well outside of reasonable.

If I had bought and reviewed the 451 when I first learned about it, it would have my unreserved recommendation. What a difference a couple years and $25 can make! The 451 is still a competitive knife in a lot of respects. The materials are simple but very well-executed. It’s nice and light for its size without sacrificing any sort of durability. And personally, I think it’s a really cool-looking knife. I can’t say that the 451 is a must-buy, but definitely don’t ignore this knife when you’re looking for something big and bold.

I recommend purchasing the Freeman Outdoor Gear 451 Flipper at Amazon, KnifeArt, BladeHQ, or you can buy it direct from Freeman Outdoor Gear. Thanks for checking out the review.

Hogue EX04 Review

by Dan Jackson 5 Comments

Last Updated: August 4, 2019
It’s fun covering the latest knife trends. Case in point, the whole titanium flipper framelock schtick has has been an absolute blast. That said, I love it when a knife company completely bucks the trend and comes out with something that is bold, inventive and well executed.

Hogue EX04

No products found.

Without spoiling the review for you, the Hogue EX04 is just that knife, and is one of the more interesting blades I’ve had the pleasure of handling in 2013. I must not be the only one who feels that way, as the EX04 won American-made knife of the year at the 2013 Blade Show.

Designed by world renown custom knifemaker Allen Elischewitz the EX04 marries an intriguing design with the same precision manufacturing and technical excellence that I gushed over when I penned my first Hogue review on the EX01. From the custom hardware down to the mirror polished edge, there is a lot to discuss with this knife, so lets get right into it.

General Dimensions and Blade Details

The EX04 comes in 2 sizes, the 3.5″ bladed version, shown here, and a version with a 4″ blade. My knife has an overall length of 8″ and weighs 4.48oz. I trend towards smaller knives for daily use, and found the 3.5″ version a good choice for urban EDC. That said, there is certainly enough knife here for use as a dedicated work or “tactical” knife.

The EX04 comes in 2 blade shapes, an upswept variant (shown here) and one with a modified wharncliffe blade. Both feature a unique double grind; a first for a production knife. I spoke with Allen Elischewitz about this personally, and he told me Hogue went to great lengths to consistently pull this unique blade geometry. I can’t say it does much functionally (although the knife is ground thin and cuts extremely well), but it is definitely a very cool detail that I really enjoy.

Hogue EX04 Blade

Hogue went with good ole 154CM which is an American stainless steel regular readers and knife aficionados should be well acquainted with. I have had a lot of good experience with 154CM, including Hogue’s 154CM when I reviewed the EX01 a while back. This time around I wanted to perform some more formal testing. The knife edge held up very well in performing a variety of EDC tasks including cutting rope, cardboard, and some basic carving. This is a useful blade shape made out of a nice balanced steel, and will provide years and years of service with very little maintenance.

Handle, Ergonomics, and Pocket Clip

The EX04 benefits from a full, sculpted G10 handle. There are no liners, although there are stainless steel bolsters that also function as washers. Like the rest of the knife the handle is superbly finished. The G10 is smooth and well contoured. The major hardware is silver and has been given a matte finish. Everything is just super refined on this knife – even the lanyard hole has been elegantly integrated.

Hogue EX04 Handle

From an ergonomic standpoint the EX04 continues to impress me. The simple sloping curves of the handle are also 3d contoured and lightly textured, which provides a good balance of comfort and grip. There is a distinct absence of jimping on the knife, which makes it very comfortable and practical for normal use. Mall ninjas will cringe at this obvious “oversight”, but as someone that actually likes to use his knife I assure you that the lack of jimping is actually a good thing.

Hogue EX04 Pocket Clip

The pocket clip is the same large spoon style offering found on the EX01. This time it has been given a durable black coating for a more discrete appearance. Some will probably find issue with the bulbous nature of the clip, but I think it’s practical and works well. The knife carries nicely in the pocket – it’s slim and lightweight and is the kind of I knife that I want to carry. If I were to give the clip a demerit, it would be for the right side tip up only carry. I understand that there may have been some design limitations requiring this clip placement, but for me tip up carry would have been preferable.

Lock and Deployment

The EX04 has ambidextrous thumb studs for deployment. They are easy to get at and the knife snaps open smoothly and crisply with little effort. An interesting feature of this knife is the absence of any kind of washer or bearing system. Instead, the blade mates up directly to stainless steel bolster plates that both reinforce the knife and serve as the “washers” for the blade to glide against. In practice this works very well, as evidenced by the very smooth and satisfying action.

Hogue EX04 in Hand

As I mentioned in the intro, the EX04 makes use of a button lock to secure the blade. It’s a nice departure from the liner and frame locks that creep into many of my folding knife reviews, and Allen has gone to great lengths to ensure that the EX04 came with a robust and reliable lock. My lock occasionally sticks a little bit. I am not sure if I need to clean it, lubricate it, or break it in more, but I do experience a little stick in the button lock from time to time.

The knife also comes with an external safety switch that locks the knife open. On the EX01 I found that the safety was too easy to engage, and would inadvertently lock the knife open, but I was relieved to find that they have made the safety button much more purposeful. It doesn’t engage accidentally, and you really need to consciously push it to lock open the knife.

Hogue EX04 Review – Final Thoughts

The EX04 is a beautiful knife. I gave it a glowing review, and I think it’s well deserved. The knife has a unique design, has been flawlessly executed, and is very practical to carry and use. If I were to make suggestions, it would be to find a way to enable tip up carry.

Besides that, this is nothing short of an awesome knife, one that I find a true pleasure to have in both my collection and my pocket. It is a premium offering, and commands a premium price tag, but this is another one of those instances where you get what you pay for.

At the time of updating this review (end of 2015) the EX-04 remains one of my favorite 3.5″ folders. It’s a beautiful tool that speaks to me on a number of different levels. Highly recommended.

No products found.

I recommend purchasing the Hogue EX04 at Amazon or BladeHQ. Thanks for checking out the review!

Hogue EX01 Review

by Dan Jackson 14 Comments

Last Updated: March 9, 2019
Hogue, a company best known for their gun grips and rifle stocks, has recently entered the realm of high end production knives. This is a pretty bold move for any company. After all, to quote Borormir in the the Lord of the Rings, “one does not simply start manufacturing knives” …or something like that.

So Hogue teamed up with one of the best in the business – award winning knifemaker Allen Elishewitz. Quite frankly, the results of this collaboration are extremely impressive. This is a very nice knife by anyone’s standards, and it’s hard to believe Hogue has never made a blade before. I had to acquire one of their knives for review. So lets take a closer look at the EX01, the knife that put them on the map.

General Dimensions and Blade Details

The EX01 comes in two different sizes (3.5″ and 4″ blades), with two different blade shapes (drop point and tanto), and two different handle materials (G10 or aluminum). Shown here is the 3.5″ model drop point with a G10 handle. This particular knife has an overall length of 8″, and 3.5″ blade and it weighs 4.3 ounces. Its aluminum counterpart weighs slightly more at 4.6 ounces, but tends to retail for slightly less. All of the EX01 folders are made in the USA.

The 4″ version of the knife has an overall length of 8.875″ and weighs 5.1 ounces (5.6 for the aluminum version). I selected the 3.5″ model because I wanted to use the knife for every day carry, and I am very happy with that decision. The knife carries well, feels light for its size, and the drop point version is reasonably unassuming. The 4″ version strikes me as a bit much for EDC, but that is a choice that ultimately you will have to make.

The drop point version of the knife is nicely executed. You have a high flat grind with a long lean swedge that falls into a sturdy tip with an edge that has a good amount of belly. Speaking of the edge, the EX01 comes with the nicest edge I have ever seen on a production blade. It is a full mirror polished edge – perfectly formed, nice and even. Apparently these are all done by hand. With most production level knives the edge grinds are usually a little off, and some can be downright sloppy. Needless to say that wasn’t the case with this knife. And yes, the knife came extremely sharp. I guess the only problem is while I can sharpen a knife ok, I will not be able to maintain that mirrored edge with my usual stones. My advice is to instead try and maintain the edge with a strop while you can.

Hogue EXO1 Blade

The tanto version of the knife is quite striking, featuring a wicked raised spine, and downward sloping blade. I would not mind adding a tanto EX01 to the collection at some point either!

Hogue EXO1 Tanto Blade

Hogue went with tried and true 154CM for the blade steel. This particular 154CM has been cryogenically heat treated to 57-59 HRc. It takes a nice edge, and has held onto it after a good amount of use. I’m not saying it’s a super steel, but I have always been a fan of 154CM. Here my thoughts are no different. Not only does it polish up beautifully, it also stonewashes very nicely – as evidenced by the handsome tumbled finish on the EX01.

Handle, Ergonomics and Pocket Clip

The EX01 is offered with either an aluminum or G10 handle. Hogue calls their G10 (shown here) “G-mascus.” Really it’s just layered G10 with some waves in it, finished to bring out a faux damascus look. Personally, I prefer the less busy look of regular G10, and probably should have gone with the aluminum version of the knife. That said, the G-mascus is a little different, and I’m some sure will like the effect.

More importantly the handle is superbly constructed. It’s made from 2 pieces of G10, and has been bolted together along with partial stainless steel liners. I love the hardware Hogue selected for the button lock, pivot, and safety. The bright stainless steel contrasts nicely with the handles, and the whole production just oozes of quality. The design features a lanyard pin, which is an elegant alternative to your more common lanyard hole. All in all construction is very solid, and the knife is beautifully finished.

Hogue EXO1 Handle

In hand the EX01 is a solid performer – comfortable and capable. Allen apparently has a strong martial arts background, and I can see this in his “ergonomic plan.” The position of the finger choil sets you back on the knife a bit to maximize reach. In this position the EX01 feels very comfortable, with your palm melting into the rounded pommel, and your finger sliding confidently around the choil. There is some jimping along the back of the knife. It’s not super aggressive, but provides some grip and feedback. You can choke up on the handle, and that works well too. The knife feels very good in a reverse grip as well.

Hogue EXO1 Pocket Clip

The pocket clip is an interesting and almost feminine contrast to the rest of the knife (especially the sharp lines of the tanto version). Rounded and bulbous, this spoon-style clip is securely held in place with 3 screws, and is tapped for right side tip up / tip down carry. Despite the contrast this is a nice pocket clip – secure and easy to use. It rides reasonably low, and is easy to insert and remove from the pocket. I really like how the EX01 carries (at least the 3.5″ version). The knife is light and comfortable, and I quickly forget it is on me. I think it’s a great choice for EDC.

Deployment and Lockup

The EX01 makes use of ambidextrous thumbstuds to open the blade. The thumbstuds are nicely positioned, and it is very easy to pop the blade out with your thumb. Deployment is both fast and smooth thanks to a unique design where large stainless steel washers are molded into the partial liners of the G10 handle. According to Allen these integral washers will burnish over time, and the knife will get smoother and smoother. The aluminum version does not have any liners. Instead, a raised portion of the type 3 hard anodized finish mates directly with the tang of the blade. Type 3 hard anodizing is extremely tough, and like the stainless steel washers it will burnish over time. Either way, deployment will be smooth, fast, reliable, and durable straight out of the box.

Hogue EXO1 Spine

The EX01 makes use of a button lock to secure the blade open. The button lock has been nicely implemented. Lockup is very sturdy, and firm (but reasonable) pressure is required to disengage it. In practice the lock feels strong, and it has worked well for EDC tasks. I would put it right up there with an axis lock or compression lock for regular use. There is an added external safety that can be used to lock the knife open. Personally, I’m not a huge fan of external safeties, and I find that this one has got in the way on more than one occasion. It can be removed, but the handle doesn’t look as good without it.

Blade retention (or the “detent”) is pretty good on this knife. I had no issues with the knife opening accidentally in pocket, but if I wanted I could snap the knife open with a firm flick of the wrist.

Hogue EX01 Review – Final Thoughts

The EX01 strikes me as a big win for Hogue. I find it especially incredible considering that this is their first attempt at making a production knife.

The EX01 is a solid design, with a lot of interesting details. Stuff like matching circular hardware and thumb studs, the lanyard pin, the way the 2 piece handle perfectly fits together, the integral washers, the perfect blade centering, and of course the mirror polished edge all add up to something special and unique. There is an enormous amount of attention to detail, and Allen Elishewitz has provided a thoughtful design to lay the foundation. The only minor issues I could come up with is that I think the “G-mascus” is kind of hokey, and I could live without the external safety. Some might find the pocket clip too large or funky, but it wasn’t an issue for me. If that is the worst I have to say about the EX01 it leads me to believe Hogue did a damn fine job.

And when you consider how this knife sells for as low as $150, well it really is mind blowing. The fit and finish is outstanding, blowing something like the Paramilitary 2 out of the water. The fact that this knife is manufactured in the USA, is so well made, and features such a thoughtful design make it an instant classic in my book. Highly recommended.
