Spyderco Endura 4 Lightweight FFG C10FPBK — Full-Flat-Ground Slicing Performance
The Spyderco Endura 4 Lightweight FFG C10FPBK takes the classic Endura platform and swaps the standard saber grind for a full-flat grind. The bevel runs all the way from the spine to the edge, thinning the blade behind the cutting edge across its whole height. The result is a noticeably better slicer than the saber-ground C10PBK — the grind is the one thing that separates these two models, so pick the FFG if cutting efficiency matters more to you than tip bulk.
The 3.8" VG-10 blade sits in a black fiberglass-reinforced nylon (FRN) handle with Bi-Directional Texture™ molding and nested, skeletonized stainless steel liners. Removing that extra steel from the blade also trims the weight to just 3.3 oz, lighter than the saber-ground version. A proven back lock holds it open and the four-position clip carries tip-up or tip-down, either side. A superb, unfussy EDC pocket knife made in Japan.

Frequently Asked Questions
What does FFG mean, and how is this different from the C10PBK?
FFG stands for full-flat ground. On the Spyderco Endura 4 Lightweight FFG C10FPBK the blade bevel begins at the spine and tapers continuously to the edge, so the blade is thinner behind the edge along its full height. The C10PBK is saber ground, with the bevel starting partway down the blade. Grind is the sole difference: the Spyderco Endura 4 Lightweight FFG C10FPBK slices better and weighs 3.3 oz, while the saber version trades that for a thicker, stronger cross-section.
How does the back lock work?
The Spyderco Endura 4 Lightweight FFG C10FPBK uses a back lock, in which a rocker bar along the spine seats into a notch in the blade tang once the blade is fully open. Press the exposed midpoint of that bar to release it and fold the blade closed. Since the release is nowhere near the blade path, the Spyderco Endura 4 Lightweight FFG C10FPBK closes safely with either hand.
What steel is the blade made from?
The Spyderco Endura 4 Lightweight FFG C10FPBK is built around VG-10, a Japanese stainless steel known for fine edge-taking and good corrosion resistance. Paired with the full-flat grind, VG-10 lets the Spyderco Endura 4 Lightweight FFG C10FPBK get very thin and very sharp without becoming difficult to maintain.
How do I sharpen this knife?
The Spyderco Endura 4 Lightweight FFG C10FPBK has a PlainEdge blade, so any guided sharpener, ceramic rod, or waterstone will work. Follow the existing bevel and use light, even strokes. The thin full-flat geometry means the Spyderco Endura 4 Lightweight FFG C10FPBK usually comes back to shaving sharp with just a few passes on a fine ceramic.
Is a full-flat grind better for everyday cutting?
For most EDC tasks — food, cardboard, rope, packaging — yes. Less steel behind the edge means less material to push through the cut, so the Spyderco Endura 4 Lightweight FFG C10FPBK glides through material a saber-ground blade would wedge in. If your work involves prying or heavy tip loads, the thicker saber grind is the safer choice; otherwise the Spyderco Endura 4 Lightweight FFG C10FPBK is the more efficient cutter.
Is this knife legal to carry?
Knife laws differ by state, county, and city, and some places cap blade length or restrict locking folders. The Spyderco Endura 4 Lightweight FFG C10FPBK is a manually opened, non-automatic folder with a 3.8" blade. Confirm your local regulations before carrying the Spyderco Endura 4 Lightweight FFG C10FPBK.
Can I carry it left-handed?
Yes. The Spyderco Endura 4 Lightweight FFG C10FPBK comes with a four-position pocket clip that mounts tip-up or tip-down on either side of the handle, and the round opening hole is fully ambidextrous. Left-handed users get the same one-hand opening from the Spyderco Endura 4 Lightweight FFG C10FPBK as right-handed users.
