The Spyderco Delica 4 C11PBK is the carry-neutral plain edge Delica 4 — VG-10 Japanese stainless in a 2.875-inch full flat ground plain edge blade, Black FRN handle, and back lock, delivering the Delica 4's decades-refined compact carry performance in the most universally applicable, carry-neutral colorway at the same $100 as the Blue and Orange plain edge variants — the right Delica 4 for buyers who want plain edge VG-10 performance without any visual identity in any carry context.

The VG-10 blade is a Japanese stainless steel developed by Takefu Special Steel specifically for cutlery applications — a high-carbon, high-chromium stainless with cobalt addition that produces a well-balanced combination of edge retention, toughness, and corrosion resistance that significantly outperforms conventional budget stainless steels. VG-10 takes a fine polished edge on conventional sharpening stones and maintains it well through everyday carry use, sharpening more readily than high-vanadium PM steels and making the C11PBK the right compact EDC for buyers who want capable, maintainable stainless steel on conventional equipment. The full flat grind runs a consistent bevel from the spine to the edge across the full blade width, thinning behind the edge for maximum cutting efficiency — the geometry that makes every Delica 4 one of the best-cutting compact EDC folders at its price point. The Black FRN handle is the most universally carry-neutral colorway in the Delica 4 lineup — more invisible than Grey, less recognizable than Blue, and the absolute opposite of Orange's high-visibility character. Black FRN carries without any visual signature in any pocket, briefcase, gear bag, or professional carry context at identical price and performance to the colored variants. The distinction between the Black plain edge C11PBK and the Black combo edge C11PSBBK at $10 more is purely edge specification — the C11PBK delivers full plain edge VG-10 across the entire blade for buyers who want conventional sharpening ease across the full cutting edge, while the C11PSBBK adds a serrated heel for cordage cutting at $10 more.

• Blade: VG-10 stainless, drop point profile, satin finish, plain edge, full flat grind — Japanese cutlery stainless with well-balanced edge retention, toughness, and corrosion resistance; full flat grind maximizes cutting efficiency; plain edge sharpens on conventional flat stones and guided systems across the full blade length
• Handle: Black FRN (fiberglass-reinforced nylon), textured bidirectional grip, compact Delica 4 profile — chemically inert and lightweight; Black is the most carry-neutral Delica 4 colorway; carries without visual signature in any carry context
• Deployment / Lock: Back Lock via Spyderco Round Hole — back lock provides reliable blade security; ambidextrous Round Hole allows one-hand opening from any grip position
• Carry: Approximately 2.50 oz, tip-up right-hand wire clip, compact Delica 4 profile — plain edge Black at $100; same price as Blue and Orange plain edge variants; $10 less than the combo edge Black C11PSBBK
