This Spyderco Endura knife has a flat saber-ground VG-10 stainless steel blade with the Emerson Wave opening feature. The handle is blue/gray FRN.

The Endura knife features a molded FRN (fiberglass reinforced nylon) handle with Bi-Directional texturing for traction and improved ergonomics. The handle is strengthened with dual skeletonized stainless steel liners that make an anchor for all external and internal components to attach while adding sturdiness and rigidity. Phosphor bronze bushings on the blade pivot smooth out the open/close action. The pocket clip is four-way reversible for tip-up/down, left- or right-handed carry. The blade is premium VG-10 stainless steel from Seki-City Japan and has Spyderco's easy to use thumb hole for simple, efficient one-hand opening of use the blade-opening feature made popular and patented by Ernest Emerson of Emerson Knives.

The Emerson opening feature is a hook curving out the top of the knife's blade. When removing the knife from a front pocket it catches the pocket's edge quickly opening the knife blade so that it's ready to use. The knife can also be taken out of the pocket without engaging the opening feature by pulling it straight up and out with your fingers on top of the closed blade.

The Endura is a larger version of the Spyderco Delica knife. Both knives have been extremely popular over the years thanks to their lightweight, high performance build and affordable price.

Customer Reviews

Great EDC Tool
Vincent O. on Oct 13, 2018

Longtime fan of Spyderco and this combo with Emerson makes opening a breeze. Feels secure in the hands with the textured grip and the blade length is ideal for bigger cutting tasks around the office.

Opens faster than my microtechs
Daniel T. on Sep 28, 2020

I've been carrying this one for over a week now, and with a little bit of practice it's the fastest and most reliable opener I own. I was a little disappointed that it didn't come in m390 steel, but it's still razor sharp right out of the box, and the wave opener works perfectly left handed.

Great EDC/Tactical Compromise
David W. on Oct 23, 2019

I own several knives for everyday carry, depending on how I'm dressed, what I'm doing and where I'm going. I bought this knife specifically for dark nights when I'm walking the dog...I live in a downtown apartment with some sketchy characters hereabouts, I'm disabled and I'm unable to run from a confrontation. I carry pepper spray but I wanted some additional peace of mind. My first choice was the Spyderco Matriarch 2, built on the same handle as the Endura 4. It's an unparalleled slashing tool but it's no good for utility use; it's made for one thing only, combat. I decided to sell the Matriarch and get the next best thing in the Endura 4 Emerson Opener, a more useful knife altogether. I have a few observations...first the VG10 steel may not be exotic, but it takes a wicked edge and holds it fairly well. It out-shaved my Paramilitary 2 and Para 3 out of the box, and they’re both premium steels. Second, with a bit of practice the Emerson Wave opener works reliably and instantly--the knife comes out of your pocket ready to use...in a high-stress situation you don't want to be fumbling to get your knife open. It's better than a switchblade because you don't have to remove it from your pocket then grope for a button. And yes, if you're into microbrews without twist-tops (like I am) the Wave makes a great bottle opener. Finally, the lockback system is one of the strongest around but is likely to be a bit of a disappointment for some Spyderco fanatics--it places spring pressure on the blade so it doesn't swing freely like a compression lock and you can forget about Spydie-flicking it open, it requires constant thumb pressure to open the blade once it's out of your pocket. I tried loosening the pivot screw a smidge but it didn't loosen up the action. All that said, it's a very well-made knife with grippy scales and a longer blade that's suited for both everyday cutting tasks and tactical use. Made in Seki-City, Japan it's just as well put together as my Golden, CO Spydercos. It's friendlier than the purpose-designed Matriarch, which kinda screams "premeditation" should you ever have to deploy it in a confrontation. Unlike the Matriarch 2, which has a fully-serrated S-shaped chisel grind, the Endura 4 has a saber-shaped drop point blade with a flat-ground edge. I dig the blue/gray color. The VG10 blade is pretty easy to touch up on a Spyderco Sharpmaker. It's a 4" knife but still compact and light enough to nestle unnoticed in your pocket until you need it...and when you do need it, it's ready to go instantly. The Wave feature is not only good tactically but should be useful to a farmer, a mechanic or anyone else who likes to depend on quick and easy one-hand opening. The blade length and shape is great for camping and food prep. My knife arrived perfectly centered with a perfect grind. It shaved a patch of my arm hair clean with one swipe, sharper out of the box than anything else I own. I have knives that cost much more but the Endura 4 has a well-deserved place in my EDC rotation and I carry it regularly (especially at night), or just when I'm doing cutting tasks better suited to a longer blade. At $91 the price is right. Whether it's your only knife or you're adding it to a collection, it's highly recommended...I think the only knife I like better is my Paramilitary 2 in S110V steel and it costs double.

Yes. 5/5.
Eric R. on Sep 12, 2018

Light. Thin. Quick one-handed deployment. This knife is everything an EDC should be. It feels great in hand, the jimping is incredibly functional and again that deployment - so good. I bought this after falling in love with the Matriarch 2 with the Emerson Wave, this knife has the same handle so the imprint is virtually the same - except pulling this out in public for some menial task like opening a letter doesn’t raise awkward questions. This won’t be the last knife I buy (because I have a sickness only new knives can cure), but it could easily be the only one I carry everyday for years to come. Buy this knife.

Solid EDC Option
George S. on Jan 6, 2018

This version of the Endura has a unique aesthetic, is highly functional, and the extra blade deployment options are a fun bonus. This knife has seen some rough usage and it had no problems. I am completely satisfied with it and it's a fun alternative to the other Endura's I carry.

A Classic Improved
David K. on Oct 12, 2018

I have always had lock back folders from Spyderco. Now with the addition of the Emerson Wave, it makes it that much easier to operate with either hand. The wave is perfectly cut to allow smooth deployment every time. I had a Fox with a wave that was more rounded and it would often catch one the pocket.

Everyday multi-use
SCOTT M. on Feb 18, 2020

-Opens with ease due to wave opener. -I added signet ring for better grip in self-defense situations. -Good for defense, but also cutting apples, opening boxes, etc. -Sharpens easily. -Not cheap, but not so expensive as to really be a problem if lost. -I sharpen it frequently as others have mentioned. -Best, most versatile, and quickest knife I have ever owned. Bought one for each of my kids for Christmas.

Used an Endura since 1994
Billy O. on Oct 14, 2018

The Endura is a lightweight workhorse. Sleek, fast, and dependable. It's also a great entry point for anyone interested in Spyderco knives.

10 years later
Jeremy V. on Nov 3, 2018

I have been carrying this for about 10 years (aproximatly). The endura wave has never let me down. As a police officer, i have used this for many tasks it was never inteded. I have sharpened this so many times it’s nearly due replacing. I have tried other knives and keep coming back to this. The lock has never failed. The blade holds an edge very well. The scales provide very good traction. The wave feature works very well, it also works well as a bottle opener. This was my first spyderco, I have bought several since.

May be the best EDC for personal protection.
Eric J. on Feb 1, 2015

The Emerson Wave on this Spydey, and the Delica Wave, is larger than on any Emerson product. The ergonomics are such that reliable auto deploy with an authoritative snap makes this blade like no other. The blade shape and size is better than the standard Endura. Very light weight. High Spydey quality. Great color. Will not disappoint.

Great combo
dale o. on Jan 19, 2018

Spyderco an emerson combo! Great construction of spyderco an emerson wave makes this a outstanding EDC. Light my usual dress up knife.

Update review
Larry M. on Aug 23, 2016

I've gone from almost hating this knife to loving it. It's broken in nicely and is super sharp. At first the scales felt like cheap plastic, but I've grown to appreciate how "grippy" it is. Not a great edc only because of its blade design, but it's my go to knife on days I cannot Carry a firearm. And the wave feature is so much fun!

Better than Emerson
Grayson V. on Jan 5, 2018

This has better fit and finish than any actual Emerson, and the wave works better. The way the wave is done makes it much easier to snag on the pocket. Amazing knife

Awesome Knife!
Brett T. on Oct 12, 2018

I've been carrying this knife for four months now and I couldn't be happier. Quick deployment and feels great doing all cutting with it. I added the Wise Men Co. signet ring for a bit of customization and made this knife even more awesome!

Big, big knife
Brian D. on Mar 14, 2019

Nice knife. Just a bigger version of the Delica. I like this version with the thicker blade more than the thinner blade (flat grind?). Feels better having a little thicker blade stock on such a long blade. Wave feature works great. Can occasionally be a problem if you want to take the knife out without opening it immediately. Just have to be aware of it.

Replacement for a lost one
Bill C. on Aug 18, 2019

I love this knife! The overall shape of it, the way it cuts, the wave function, and the way it sits in my pocket are the major positive attributes. I carried one for eight years, and another for maybe four years before that. The only reason I gave it four stars over five is that the manufacturing quality seems to have slipped a bit. The last two had perfect grinds, this one has a bump on the edge just before the plunge line that I had to take care of before It was as good as the others. I'd also have to say that it wasn't as sharp as the others out of the box. I'm still happy to have it and happy to carry it. During my mourning period while I searched frantically for it, I carried a Benchmade Griptilian, a great knife in it's own right, but it couldn't fully replace the Endura for me. I sure wish they'd make an Endura in an upgraded steel with the Wave...I'd snap it up in a second!

What a knife should be
Nic G. on Oct 12, 2018

My favorite spyderco to date. Once you go emerson/wave opener, you can't go back. I carry this when out in plainclothes, and the quick deployment gives me a great degree of confidence. Pros: -Lightweight -EMERSON OPENER! -Super affordable -Customizable -Spyderco. Cons: -Lock-up can fail if you draw it too fast/forcefull -Non-neutral handle ergonomics

Work edc
Jorge R. on Oct 12, 2018

This is my work edc, very solid overall knife. Not the prettiest blade shape but very effective. Feels great in hand and nice blade size. Same problem as many other spydercos, to much handle sticks out of the pocket.

Great for heavier use
Travis M. on Oct 15, 2018

The saber grind on the waved version makes it a little nicer for tasks that you may want a slightly stouter blade for such as construction and things that don't require a finer slicing edge.
