Product Description

The Spyderco Delica 4 C11PCBL is the proprietary steel Delica 4 — CPM SPY27, Spyderco's own powder metallurgy stainless steel developed in collaboration with Carpenter, in a 2.90-inch full flat ground plain edge blade, Cobalt Blue FRN handle, and back lock, delivering a steel specification exclusive to Spyderco that outperforms VG-10 in edge retention and corrosion resistance in the compact Delica 4 platform in a distinctive Cobalt Blue FRN colorway at $125 — the right Delica 4 for buyers who want Spyderco's proprietary performance upgrade over VG-10 in the compact back lock platform.

The CPM SPY27 blade is Spyderco's proprietary powder metallurgy stainless steel developed in collaboration with Carpenter — a steel formulated specifically for Spyderco's production requirements, not available in any other manufacturer's production knives. CPM SPY27 delivers meaningfully better edge retention than VG-10 through its higher carbon and vanadium content, while maintaining stainless corrosion resistance that requires no special care beyond normal knife maintenance — the steel upgrade over VG-10 that delivers more cutting sessions between sharpenings without the non-stainless care requirements of K390 or the specialized diamond sharpening demands of CPM S90V. CPM SPY27 sharpens on conventional diamond stones and quality ceramic abrasives more readily than the highest-vanadium PM steels, making it maintainable at home with accessible sharpening equipment. The proprietary nature of CPM SPY27 — available only in Spyderco production — makes the C11PCBL one of the few compact EDC folders where the steel itself is an exclusive Spyderco specification, adding collector and enthusiast appeal beyond the practical performance upgrade. The full flat grind maximizes CPM SPY27's cutting geometry by thinning behind the edge across the full blade width — the same geometry that makes every Delica 4 one of the most efficient slicing compact EDC folders at its price point, here applied to a steel that holds the resulting edge geometry longer than VG-10. The Cobalt Blue FRN handle is a visually distinct colorway from the standard Blue FRN of the VG-10 C11FPBL — a deeper, richer blue that distinguishes the SPY27 variant in the Delica 4 lineup and signals the premium steel specification to buyers familiar with the Delica 4 color coding.

• Blade: CPM SPY27 proprietary Spyderco powder metallurgy stainless, drop point profile, satin finish, plain edge, full flat grind — Spyderco-exclusive PM stainless with better edge retention than VG-10; maintains stainless corrosion resistance requiring no special care; sharpens on diamond stones and quality ceramics; exclusive to Spyderco production
• Handle: Cobalt Blue FRN (fiberglass-reinforced nylon), textured bidirectional grip, compact Delica 4 profile — chemically inert and lightweight; Cobalt Blue is visually distinct from standard Blue FRN; signals SPY27 premium steel specification in the Delica 4 lineup
• 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 — CPM SPY27 proprietary steel at $125; $25 more than VG-10 plain edge FRN variants; $5 more than the stainless handle C11P

Ideal For

Performance-focused EDC buyers who want a meaningful steel upgrade over VG-10 in the compact Delica 4 platform without moving to the non-stainless care requirements of K390 or the specialized sharpening demands of the highest-vanadium PM steels — the C11PCBL at $125 delivers CPM SPY27's better edge retention and stainless corrosion resistance in the same ultralight FRN Delica 4 back lock package, maintainable on diamond stones at home, at $25 more than VG-10. Spyderco enthusiasts and steel-focused collectors who want Spyderco's proprietary exclusive steel in the compact Delica 4 platform — CPM SPY27's availability only in Spyderco production makes the C11PCBL a specification that cannot be matched in any other manufacturer's compact back lock folder, adding a distinct collector dimension alongside its practical performance advantage. Buyers choosing between CPM SPY27 C11PCBL and VG-10 Blue C11FPBL at $25 less who want a meaningful stainless steel upgrade with conventional FRN Delica 4 carry character — CPM SPY27 outperforms VG-10 in edge retention while maintaining stainless corrosion resistance and the same ultralight FRN Delica 4 carry profile, at $25 more.

CPM SPY27 — Spyderco's proprietary PM stainless exclusive to Spyderco production — with better edge retention than VG-10 and stainless corrosion resistance requiring no special maintenance, a full flat grind that maximizes cutting geometry across the 2.90-inch blade, Cobalt Blue FRN that visually distinguishes the SPY27 Delica 4 in the lineup, and the back lock in Japan's most refined compact production folder — the Spyderco Delica 4 C11PCBL is the proprietary steel Delica 4 at $125.
