Description The Spyderco Efficient Black Blade is a compact folding knife designed for everyday cutting jobs where a practical blade, secure grip and convenient pocket carry matter. This all-black version features a 2.99-inch drop-point blade made from 8Cr13MoV stainless steel. Its black oxide coating is coordinated with the coated liners, clip and handle hardware for a subdued, uniform appearance. The CombinationEdge configuration places Spyderco serrations near the heel of the blade while retaining a plain section toward the tip, giving the knife two useful cutting styles in one edge. The serrated portion is suited to working through fibrous materials, while the plain portion supports controlled utility cuts and general slicing. A full-flat grind provides efficient cutting geometry across the broad drop-point profile, and Spydercos round opening hole allows direct manual access to the blade. The handle combines peel-ply-textured black G-10 scales with full, skeletonized stainless steel liners and a stainless steel back spacer. Its curved shape follows the blades spine and incorporates an index-finger choil, creating a compact platform with useful control during routine work. The liners also form the knifes LinerLock mechanism, which holds the blade open during use and remains straightforward to release when the job is finished. A lined lanyard hole offers another carry or retention option. For pocket carry, the Efficient is equipped with a reversible deep-pocket wire clip configured for tip-up placement on either side of the handle, making it suitable for left- or right-side carry. Measuring 4.13 inches closed and 6.97 inches overall, this Efficient balances useful cutting capability with a manageable size for a pocket, work bag, outdoor kit or everyday gear loadout.
