This Spyderco Endura knife has a partially serrated flat saber-ground VG-10 stainless steel blade that is black titanium carbonitride coated. Black FRN handle.

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.

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.

Probably my best friend!

Bought this model Endura years ago and it has not failed me yet. It's been through just about everything I've been through at work on shift and when I'm off. I've considered replacing it with other knives, but this knife is like my wife, it does everything well and is very forgiving. Buy one, you won't be disappointed.

The tactical life!

I bought the endura to try out the signet ring with it. I don't have any complain about the endura overall it's a best knife to have as a edc or a part of a collection. It became even better when I placed the wiseman signet ring on it.
Carried for years

I exclusively carried this for years; I like the combo edge for versatility, slim profile for daily pocket carry, and it wears well with use. The handle while very comfortable seems a bit long but that is debatable. The back lock isn't the most fun to play with or easy to use one handed but is reliable. You won't be disappointed with it

This was my first back lock knife and I'm sry happy with it. The VG-10 steel hold a blade really well and it's super strong, I know this is a work horse. Treat it as one
Excellent Knife
Ed S.
This is my first Spyderco and came away impressed with the quality and sharpness. I really like the backlock. There's no doubt about this being locked in when you hear that audible snap. Not a click, it snaps in place. The handle is thin and ergonomically perfect for those with small to medium hands. Being a lefty I appreciate the ability to move the clip to the correct side in addition to having the option for tip up or down. Overall, a fantastic knife with quality steel.
Knife perfection

Purchased this knife in full flat ground blade style and loved it so much I bought this model from friend. This specific model is IMO one of the best knives ever made. I take it fishing and camping, i swim and hang out in the sand with it. It still functions perfectly. The serrations are so useful for cutting through ropes, hard plastic, wood, and just about anything and are still sharp. This knife goes underwater constantly with me and never rusts, I wish they would make a salt version tho. Holding this knife will give you confidence like no other. So comfortable in the hand, yet grips like no other knife I've ever held. Bladehq don't ever stop stocking this knife!!!
Outstanding lockback
USA #.
I have over 50 high quality knives. I have carried this knife more than any over the years. It is worn and scuffed up. It is STILL razor sharp and performs flawlessly. Solid lockup and the VG 10 steel is great. I bought a matching Delica a week later. It's no frills and will cut anything you need it to. I love the handle. The grip pattern is exceptional. Extremely lightweight and perfect for edc. I adore this knife. Superb quality. It's a must have in any combination. Flat grind etc. It's amazing.
Awesome EDC, duty knife.

Just received my Endura 4. Purchased it to carry on duty as a LEO. First impression; awesome knife! Nice heavy duty blade, strong lock up, super sharp and looks great. This is my first Spyderco. Great packaging and fast shipping by bladehq. Future knife purchases will be bought only through bladehq. Thanks!
