Product Description

The Spyderco Delica 4 Lightweight in K390 is the pocket knife that refuses to make compromises — pairing one of the most technically advanced tool steels ever put on a production folder with the featherlight portability that made the Delica a global EDC icon. This is not the Delica you have carried before. This is the Delica at its absolute best.

For over three decades the Delica 4 has been Spyderco's definitive answer to the question: what is the best lightweight everyday carry knife? The answer has always been the same frame — slim, pocketable, ambidextrous, and endlessly reliable. What changes with the C11FPK390 is the steel, and the change is significant. The 2.87" drop-point blade is ground from Bohler K390 Microclean, a powder metallurgy tool steel originally engineered for cold-work industrial applications where edge retention under extreme stress is non-negotiable. In a knife blade, K390 delivers edge-holding performance that puts it in the same conversation as CPM MagnaCut and M390 — but with a toughness profile that makes it particularly well suited for hard daily use. The full flat grind maximizes slicing efficiency, pulling the blade geometry thin enough to excel at everything from food prep to precision cutting tasks, while the satin finish keeps the aesthetics clean and the maintenance straightforward. The signature Blue FRN handle is as light as it looks — just 2.50 oz total — with Spyderco's trademark bi-directional texturing providing a secure grip in any condition, wet or dry.

• Blade: Bohler K390 Microclean powder tool steel with a full flat grind for exceptional slicing performance, satin finish, and a versatile drop-point profile optimized for everyday cutting tasks.
• Handle: Lightweight Blue FRN (Fiberglass Reinforced Nylon) with bi-directional texturing for positive grip in all conditions — paired with skeletonized stainless steel liners for strength without weight.
• Deployment/Lock: One-handed deployment via Spyderco's iconic Trademark Round Hole™ and a proven, reliable Back Lock mechanism that closes safely and positively every time.
• Carry: An ultralight 2.50 oz with a four-position reversible pocket clip — tip-up or tip-down, left or right hand — for complete ambidextrous carry flexibility and a lanyard hole for additional retention options.

Also ideal as a dedicated food-prep or culinary EDC where the full flat grind's slicing geometry truly shines.
