Spyderco Endura 4 Lightweight C10PBK — The Saber-Ground EDC Standard
Since 1990 the Endura has been one of the most recognized folding knives on the planet, and the Spyderco Endura 4 Lightweight C10PBK is the configuration that defines the line. Its 3.8" VG-10 blade is saber ground — the primary bevel starts partway down the blade rather than at the spine — which leaves more steel behind the edge for a stronger tip and a stiffer blade. If you want the flat-ground version instead, that is the separate C10FPBK model; the grind is the difference between them.
The black fiberglass-reinforced nylon (FRN) handle carries Spyderco's Bi-Directional Texture™ pattern over nested, skeletonized stainless steel liners, so the knife stays rigid at just 3.7 oz. A sturdy back lock secures the blade, and the four-position pocket clip lets you carry tip-up or tip-down, left or right. It is a genuinely no-nonsense EDC pocket knife, still made in Seki-City, Japan.

Frequently Asked Questions
What is the difference between the C10PBK and the C10FPBK Endura 4?
The grind. The Spyderco Endura 4 Lightweight C10PBK has a saber-ground blade, where the bevel begins partway down the blade for extra strength and tip stiffness. The C10FPBK is full-flat ground, with the bevel running from the spine for thinner slicing geometry. Both use VG-10 steel and a back lock; the Spyderco Endura 4 Lightweight C10PBK is the stouter of the two and runs slightly heavier at 3.7 oz.
How does the back lock on this knife work?
The Spyderco Endura 4 Lightweight C10PBK uses a back lock: a spine-mounted rocker bar drops into a notch in the blade tang when the blade opens. To close it, press the exposed section of the rocker bar in the middle of the spine and fold the blade shut. Because the release sits away from the blade path, the back lock on the Spyderco Endura 4 Lightweight C10PBK is easy to operate with either hand.
What kind of steel is the blade?
The Spyderco Endura 4 Lightweight C10PBK uses VG-10, a Japanese stainless steel with a well-earned reputation for taking a very fine edge and resisting corrosion. It is a forgiving steel to maintain, which is a large part of why the Spyderco Endura 4 Lightweight C10PBK has stayed a benchmark EDC pocket knife for decades.
How do I sharpen it?
Because the Spyderco Endura 4 Lightweight C10PBK has a PlainEdge blade, any standard sharpening system works — guided-rod sharpeners, ceramic rods, or waterstones. Match the existing bevel angle and work in light, even passes. VG-10 responds quickly, so the Spyderco Endura 4 Lightweight C10PBK rarely needs more than a few strokes on a ceramic rod to bring the edge back.
What is a saber grind, and why choose one?
A saber grind starts the blade bevel partway down the blade face instead of at the spine, leaving a thicker cross-section behind the edge. On the Spyderco Endura 4 Lightweight C10PBK that means more lateral strength and a more robust tip, at the cost of a little slicing efficiency versus a flat grind. It is the right pick if the Spyderco Endura 4 Lightweight C10PBK will see harder use than pure food-prep or box-cutting.
Is it legal to carry?
Knife laws vary widely by state, county, and city, and some jurisdictions restrict blade length or locking folders. The Spyderco Endura 4 Lightweight C10PBK is a manually opened, non-automatic folder with a 3.8" blade. Check your local statutes before carrying the Spyderco Endura 4 Lightweight C10PBK, since a length limit in your area may apply.
How is the pocket clip configured?
The Spyderco Endura 4 Lightweight C10PBK ships with a four-position pocket clip that can be mounted tip-up or tip-down on either side of the handle. That ambidextrous setup, combined with the round opening hole, makes the Spyderco Endura 4 Lightweight C10PBK equally practical for left- and right-handed carry.
