Ah, the Spyderco Delica – is there a more classic EDC design? Well, if we are talking about modern folding knives, I’d argue there really isn’t. One of Spyderco’s most popular knives, the Delica 4, is the brand’s bread and butter; a simple, reliable folding knife that is built with easy carry and utility in mind.

Many will wonder why it took me so long to review the Delica. Even the relatively new fourth generation version (hence Delica “4”) has been out for a while. The truth is, there are too many knives and too little time. Also, I reviewed the Endura 4 a while back, and since the knives are so similar it took me a while to get around to the Delica. Better late than never however, and I finally intend to give this knife the attention it deserves.

General Dimensions and Blade Details

The Delica has an overall length of 7-1/8″, a 2-7/8″ blade, weighs 2.5 ounces, and is made in Japan. This is a slim and lightweight design, perfect for every day carry (EDC).

The Delica features a leaf shaped blade, and is defined by its large thumb hole. This is a classic Spyderco blade shape. For the uninitiated the blade will almost look goofy, but for those that appreciate this unique aesthetic it’s a beautiful sight to behold. The 4th generation has been given a full flat grind and a beautiful satin finish. All in all, it’s a pretty unremarkable blade, just a simple look that is designed for performance. The tip is fine and lacks reinforcement so the user needs to take care and avoid any prying tasks.

The standard Delica comes with a VG-10 blade. VG-10 is a Japanese stainless steel. This is a serviceable mid range steel. It’s easy to sharpen, takes a fine edge, and holds on to it for a reasonable amount of time. It’s not a super steel, but it’s a step above budget blade steels like AUS-8 and 8Cr13MoV.

Handle, Ergonomics and Pocket Clip

The handle on the 4th gen is fiberglass reinforced nylon (FRN) over full stainless steel liners. The liners have been nested inside the scales and are thoroughly milled out. This keeps the knife very slim and lightweight. Everything has been bolted together so you can take the knife apart if needed. Since the Delica has a backlock, this is a closed back design.

You can get the Delica 4 in a variety of colors including blue, purple, brown, white, green and of course black. Collectors like this, and I admit the choice of color is fun. I went with green for mine, it’s a friendly color that stands out from the sea of black handled knives in my dresser drawer.

The ergonomics on the latest generation of the Delica are quite nice. This is no surprise for a design that has spent over 20 years in the Spyderco catalog. That said, there have been a number of refinements to improve the already solid foundation. The FRN scales have been given what Spyderco calls a “bi-directional texture” – this allows for a slip resistant grip at any angle. Jimping extends from the back of the handle to the top of the thumb ramp, and it locks the thumb in nicely. The handle shape is smoothed on the edges and has plenty of room for large hands. This handle is very comfortable in all the normal grips.

The pocket clip is discrete and offers unparalleled carry options. This is a standard “spoon” style pocket clip and has been coated flat black. This is a removable clip and can be positioned on any of the 4 corners of the knife with 3 torx screws. I love the versatility of this clip, this is a truly ambidextrous design. Clip retention is excellent and the knife rides low in the pocket. The only negative I could find is that the coating does wear off with use, which happens with pretty much any pocket clip.

Deployment and Lockup

It should be no surprise that the Delica uses a thumb hole for deployment. This particular spyderhole has a diameter of 13mm. I have found this to be a good size for both gloved and bare hands. Deployment is smooth and the knife can be flicked out with a practiced hand.

The Delica uses a back lock located right in the middle of the handle. This is easy to access but it will take some technique to close this knife with one hand. The lock is very secure with no blade play at all. The spring on the back lock is very good so inadvertently opening the knife is highly unlikely. The Boyd dent on the lock bar helps ensure that the knife will not inadvertently close either.

Spyderco Delica 4 Review – Final Thoughts

It doesn’t take long to discover why this is one of Spyderco’s most popular designs. One thing that strikes me is how well built the knife feels. The nested liners are flush, the blade is centered, the FRN is well finished. I love the satin finished blade and shaving sharp edge.

I also can appreciate how lefty-friendly this knife is. The thumb hole, lock back and pocket clip are entirely ambidextrous. Add in the choice of colors and this really feels like a knife that was made for me.

As I struggle to find negatives about the knife, I’ll mention that at around $65, it is not a cheap knife. Especially if you are considering this as a step up from $20-30 knives. I think you get what you pay for. I would also say that it would be really nice if they made the Delica in America. These are really minor issues, and if its the worst thing I can say about the knife then it really says something.

In conclusion, the Spyderco Delica is an outstanding knife. It has been refined over decades and has become a measuring stick in the EDC knife world. If you are on the road to collecting pocket knives, the Delica 4 is a foundation blade. If you are simply looking for a practical EDC knife, then the Delica 4 fits that bill too.

The Spyderco Endura is a knife that you won’t fully appreciate until you hold it in your hand. I remember when I first saw this blade at a local gun show. I had heard a lot about the Endura from friends and on various knife communities but it didn’t click until I picked it up and flicked it open. This knife has a 3.75″ blade, yet it is deceptively thin and light.

Spyderco has had the Endura in its catalog for decades, and the latest version features several refinements over its predecessors, and is offered in a variety of handle colors. As a lover of large EDC knives the Endura spoke to me, and it wasn’t long before I had one in my pocket.

General Dimensions and Blade Details

The Spyderco Endura has a 3.75″ blade, a total length of 8.75″, weighs of 3.6 ounces, and is made in Japan. The appeal to the Endura is that it is a large knife, but is still lightweight and pocketable. You can use this as an Every Day Carry (EDC) knife, although I prefer its little brother the Spyderco Delica or the Dragonfly II for suburban EDC.

Here is a size comparison with the Delica:

The Endura features a long slender blade. It’s a pretty simple drop point shape, perhaps the biggest detail is that Spyderco has produced the 4th generation Endura with a full flat grind. A full flat grind is when the knife is one continuous grind from the spine down to the secondary bevel (the bevel that the edge sits on). Full flat grinds are very common in kitchen knives because they are so effective at slicing. The Endura is a great slicer, and the long slim blade is also good at penetrating soft targets. However, you will want to take care with the tip as it is fairly thin.

Spyderco selected VG-10 for this edition of the Endura. In my opinion, this was a decent choice. VG-10 is a Japanese steel that sharpens easily, offers good edge retention, and has great corrosion resistance. There are many higher end steels on the market these days, but given the price of the knife and its intended use as a working tool, I think VG10 was a reasonable choice here.

Handle Design, Ergonomics, and Pocket Clip

The Endura has a handle made of fiberglass reinforced nylon (FRN) with nested steel liners that have been milled to reduce weight. Generally, I like the FRN handle, it keeps the knife light, is comfortable, and comes in a variety of colors, including blue, white, gray, green, brown, orange and yes, even camo. I will say that it isn’t the strongest handle design, even with the steel liners, and that is probably my biggest issue with the FRN Endura. But for light to medium use, the Endura handle should hold up well and provide the user a lot of use.

Ergonomics on the Endura are good. It’s a long knife so you have plenty of room for multiple styles of forward and reverse grips. You can set you hand back on the knife to maximize reach, or choke up and make use of the well jimped thumb ramp for detail work. The FRN has rounded and contoured corners that work well with the aggressively textured flats. The texture is Spyderco’s proprietary “bi-directional texturing” and allows for a firm grip in almost any condition. All in all, the Endura has a solid handle design backed by smart ergonomics.

The Endura has a well implemented pocket clip. It’s a standard Spyderco spoon style clip, and it has been given a black coating. The clip rides decently low and offers good retention in the pocket. I especially like how the clip can be mounted on any of the 4 corners of the knife. This is truly a well done ambidextrous pocket clip.

Deployment and Lock

The Spyderco Endura makes use of a large 13mm thumb hole for deployment. Fans of thumb holes will no doubt be very satisfied with the one on the Endura. The “Spyder Hole” is well placed and provides lots of room for your thumb. My knife opens easily with the flick of a thumb thanks to the smart design and low friction phosphor bronze washers. Spyderco also makes a waved version of the knife, so if you like that kind of deployment you could consider the waved version.

The Endura utilizes a lock back to lock the blade in place. The knife I am reviewing began developing some blade play after months of daily carry. Today the bladeplay can be removed if the pivot is tightened down further, but it makes the deployment more difficult. Having done some research I’ve concluded that slight amounts of up and down blade play are not uncommon on the Endura.

I think this is due to the design of the knife. When you have a knife as long and as lightweight as the Endura with FRN scales and nested liners, it’s just not going to be able to hold up to hard use as well as other designs. If you are looking for a more hard use folder from Spyderco, I recommend checking out the Paramilitary 2.

Speaking of the Para 2, here it is next to the Endura:

Spyderco Endura Review – Final Thoughts

The Spyderco Endura has been a staple in Spyderco’s lineup for decades, and with good reason. This is a knife that is easy enough to carry every day, but big enough to be used as a serious tool or defensive option. Like with many of Spyderco’s offerings the company has been slowly refining it’s designs to improve their products and meet consumer demands. The current iteration of the Endura features an attractive full flat ground blade, a removable 4 position pocket clip, and it comes in a number of different handle colors. These are nice improvements on an already solid design that is based around Spyderco’s philosophy of making useful tools that can be appreciated every day.

I like pretty much everything about the Endura. The materials and fit and finish are both very good, I love how everything is fully ambidextrous, and the choice of handle color is fun. Generally speaking the Endura is a well thought out knife that gets the job done. Spyderco has massaged this design over the years and it remains a classic choice among enthusiasts. Although there are a lot more “gee whiz” options out there today with super steels and fancy materials, the Endura remains a no-nonsense choice for a larger EDC or tactical offering.

My only real gripe is that there is a potential for blade play to develop. For that reason I don’t recommend the Endura as a hard use tool, but rather as a light to medium use EDC knife. If you want a larger EDC or folding tactical knife that is slim and light weight, then the Endura should be high on your list of knives to consider.
