Spyderco Endura remains a classic pocket knife from the giant knife manufacturer Spyderco. It has been around for decades and is still popular among knife enthusiasts.

Its 4th generation model tries to improve the features and performance of the earlier models. But how good is it as an EDC knife? Does it deploy fast? Is the lockup great? How about the blade edge retention and cutting ability? Is the knife worth it?

This Endura 4 EDC folder review will answer all the questions you have about this folder. This will help you decide whether it fits your unique needs and expectations for an EDC knife.

Spyderco Endura 4 overview and specs

The story of Endura 4 begins in the 1990s when Spyderco produces two knives, the Endura and the Delica. The former was essentially a bigger variation of the former. When it was initially released, the knife received criticism from massing, citing its bizarre looks.

Fast forward, the knife is currently on its 4th generation as a result of Spyderco's efforts to keep improving its classic to better meet the needs of EDC enthusiasts.

This Endura 4 has a huge 3.75-inch blade made from the Japanese VG-10 stainless steel. The blade has a flat saber grind and a larger thumbhole for easy deployment.

This blade is available in plain, serrated, or combo edges.

It includes Spyderco's high-strength back lock mechanism, a 4-position pocket clip, and an FRN (fiberglass reinforced nylon) handle with bi-directional texturing. This handle comes in a variety of colors for you to choose from.

It is worth noting that this knife is made in Japan, and this is a good thing because it gives you confidence in its quality. Cheaper quality Spydercos are usually made in China using cheaper quality materials.

Spyderco kept it old-school in this knife by using the plastic FRN handle. This material has bi-directional to give you a secure and firm grip when handling the knife.

Most users also consider this texturing as more aesthetically pleasing.

The manufacturer designed this knife with a dual skeletonized stainless steel frame below the FRN handle, which helps ensure great strength while keeping the weight low.

These strong liners also act as the anchor for all the components inside and outside the handle, making it a tougher and more rigid handle.

And don't forget a lanyard hole is included in the handle. And it is wide enough to let you easily slip in a lanyard for easy knife carry.


The handle comes with bi-directional texturing that makes the knife stick on your hand and keeps it from slipping during hard use. The finger grips on the handle help guide finger placement for more secure handling.

The knife also has the perfect weight vs size ratio. This gives it a great balance and allows you to hold it in your hands for long periods of time without fatigue effect.

Handle edges are well rounded to eliminate hotspots and ensure easy use.

It is worth noting that the blade also comes with a slip-resistant jimping that gives your thumb an anchor point when using your knife for hard cutting tasks.


The pocket clip in this knife lands in a nicer, more comfortable place during handling. And this means no hotspots, further improving the overall user comfort and ergonomics.

However, a forward finger choil is missing for this knife. This would have given the knife a significant boost in ergonomics. This is especially true since this blade is only a few inches shy of 4 inches and will offer enough room for the choil.

Some of the cutting edge would have been sacrificed for this ergonomic feature to make the knife even more comfortable for you to use.


The blade length of this EDC knife is 3.75 inches, which is quite huge for an EDC knife. The blade has a nice thickness for general EDC work.

It's suitable for carrying out nearly any day-to-day cutting tasks. The blade features VG-10 steel, made in Seki City, Japan. It comes scary sharp out of box, so you'd want to handle it with care.

This steel offers great edge retention. It takes a super-fine edge easily, and sharpening it is a breeze. It has high corrosion resistance properties to minimize the rust problem.

It comes in the iconic Spyderco leaf-shaped design. This blade is black titanium carbonitride coated to reduce glares and reflections. This helps give your knife a lower profile appearance when you open it. It also adds to the blade's overall corrosion resistance.

The blade features a full-flat grind running from the sharpening choil all the way up to the tip. This gives it a thinner cutting edge and makes it a great slicing tool. The blade tip makes a nice piercing tool.

You'll find an oversized Spyderco thumb hole on this blade, which grants you a convenient one-handed opening of the knife.

The cutting edge comes in plain or serrated format to help you pick one that fits your unique applications. Or you can get it in a combo blade to allow you to enjoy the best of both worlds.

Deployment and lockup

Because it lies in the family of one of the earliest Spyderco knives, the Endura, this knife comes with Spyderco's signature thumbhole. This hole is oversized and gives you a fast method of deploying your blade.

It features bronze washers that give the blade a smooth feel when opening or closing it.

Remember that the action might feel stiff out of the box, but it smoothens out with continued use. So, don't give up on it for the first few uses.

Endura 4 features a lock-back locking mechanism that is rigid and holds your blade securely in position throughout use.

Once deployed, the blade locks in place firmly, and there's no detectable wiggle or play for the blade. This is a great achievement since most knives have some play, making it hard to use when handling tasks requiring strength and precision.

The lockup also features a Boye dent, which helps prevent accidental closing of the blade when the knife is in use.

Pocket clip

The Endura comes with an ambidextrous, 4-way pocket clip that lets you customize it according to your preferences. In other words, you can configure this clip for tip-up or tip-down carry in either right or left-hand side.

You can easily change the clip position as it's held in place by 3 Torx screws which you simply unscrew to change the clip carry configuration.

What's more, this knife has a slimmer profile and a lightweight design, which further contribute to its comfortable carry in your pocket.

Pocket clip

The pocket is black coated, just like the blade and the handle, making this knife completely disappear the moment you clip in your black or midnight blue pants or jeans.

Above all, the knife weighs only 3.6oz., making it surprisingly lightweight, given the big blade. This allows easy to carry without feeling like it's bugging you.

Fit and finish

The fit and finish are good for this EDC folder. The blade s scarp sharp out of the box. It lines up perfectly well when deployed, with no play or wiggle in any direction.  The grind is well-done and has no flaws.

It offers smooth and fast deployment and has a big blade for handling pretty much every EDC work. It holds an edge quite well and offers you multiple carry options.
