The Spyderco Delica 4 Wharncliffe C11FSWCBK is the straight-edge serrated Delica 4 — VG-10 Japanese stainless in a 2.90-inch Wharncliffe profile with SpyderEdge full serrations, Black FRN handle, and back lock, combining the Wharncliffe's completely straight cutting edge geometry with SpyderEdge's maximum push-cutting line and cordage efficiency in the most carry-neutral Black FRN build in the Delica 4 lineup — at $80, the most accessible Delica 4 in the Knifeworks lineup, $20 less than the standard plain edge VG-10 Delica 4 variants.

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. In the Wharncliffe SpyderEdge configuration, VG-10 delivers its well-balanced stainless performance across a blade geometry combination that is entirely distinct from every other Delica 4 in the lineup — neither a drop point plain edge nor a drop point combo edge, but a straight-edge serrated Wharncliffe that maximizes simultaneous cutting contact across the full blade length in every push cut. The Wharncliffe blade profile delivers a completely straight cutting edge with no belly curve, paired with a flat spine that drops linearly to the tip — the same geometry that makes the Wharncliffe the most efficient profile for SpyderEdge serrations in push-cutting applications, as the straight edge contacts rope, line, and material simultaneously across the entire blade length rather than progressively along a belly arc. Combined with SpyderEdge's full serrations, the Wharncliffe geometry creates the most aggressive push-cutting line-cutting configuration available in the Delica 4 platform — every SpyderEdge serration point contacts material simultaneously across the full straight edge in a push cut, maximizing cutting efficiency on rope, cordage, webbing, and fibrous materials without the belly compromise that a serrated drop point introduces. The Black FRN handle carries the Wharncliffe SpyderEdge Delica 4's functional specification without any visual signature — the most carry-neutral Delica 4 colorway matched to the most functionally specialized Delica 4 blade geometry at $80.

• Blade: VG-10 stainless, Wharncliffe profile, satin finish, SpyderEdge full serrated — Japanese cutlery stainless with well-balanced edge retention, toughness, and corrosion resistance; Wharncliffe straight edge maximizes simultaneous cutting contact in push cuts; SpyderEdge full serrations across the straight edge for maximum push-cutting rope and cordage efficiency; most specialized cutting configuration in the Delica 4 lineup
• 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 — Wharncliffe SpyderEdge at $80; the most accessible Delica 4 in the Knifeworks lineup, $20 less than standard plain edge VG-10 Delica 4 variants
