Spyderco Endura 4 Knife Black FRN Folder (3.75" Satin Full Serr) C10SBK

  • Satin-finished, fully-serrated drop point blade made of VG10 steel.
  • Ambidextrous thumb hole opener.
  • Black FRN handle scales.
  • Ambidextrous lockback mechanism.
  • Four-position reversible pocket clip.


This Spyderco Endura knife has a flat saber-ground VG-10 stainless steel blade that is satin finished with a fully serrated edge. The handle is black 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.

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 for my need
Morgan M. on Jun 27, 2022

I wanted a Police fully serrated model but the price held me back. I don't need a tactical knife. I found the Endura has a fully serrated model only slightly shorter for less and bought it. It's perfect for my emergency tool belt alongside a Streamlight Stinger. The knife cuts really well. Obviously, it's more of a specific use than a general use blade. It is easy to open and close one-handed, has sharp blade steel, and has enough handle to apply hand pressure without slipping. With knife prices increasing and availability decreasing I am getting the knives I want when they are available.

Great Knife!

I love this knife, I carry it daily at work for the last few years, the full serration make it cut through anything, I would highly recommend this to anyone as a EDC!

Incredible Cutting Performance

The never ending Endura
Larry i. on Oct 19, 2018

I am a spyderco guy , I still have the clip it Endura full serration model my father purchased me when I was a teen.This knife has been with me through thick and thin since 1993 every day . I have recently bought a newer spyderco simply because of the sentimental value of my EDC. All in all if your on the fence about any spyderco, just jump down and pick up the one that will make you smile and you’ll have a knife for a lifetime .. ps blade hq, wishing I could post a pic here of my Endura , the folks would be proud to see the use on this one .

Austin F. on Oct 13, 2018

I've had this knife since 2013 and man is it smooth now! after 5 years of use I have had ZERO chips in the edge whatsoever and I have cut all kinds of stuff from hay bail twine to cans to fishing line to big zip ties. A Great large folder and for the price VG10 is a great steel. The reason I purchased this knife was because when I got out of boot camp I went to the Fort Lewis Army base in Washington state and bought my first spyderco ever which was fully serrated and I CUT EVERYTHING with it. Great knife, Great price, Great size JUST GREAT ALL AROUND

Killer knife
Matt V. on Oct 12, 2018

This is the first fully serrated knife i have purchased. This thing cuts like butter and is a beautiful carry. A bit stiff at first as to expect but it has grown to be my favorite out of all 16 of my knives over the 5 month period of owning it.
