The blade on the Delica is premium K390 steel and features spine jimping that extends from the ramp to the top of the handle. The Spyderco original thumb hole on the blade allows ambidextrous one-hand opening for right or left handers and the phosphor bronze washers at the pivot make the blade action smooth. The Delica has a lightweight FRN (fiberglass reinforced nylon) handle with skeletonized stainless steel liners and a strong back lock mechanism. The handle features screw construction for quick, simple cleaning and adjustment. The FRN scales utilize Spyderco’s patented Bi-Directional Texturing to keep your hand from slipping under pressure. The pocket clip is 4-way reversible for tip-up/down and left/right carry.
