The “Thin Red Line” series from Spyderco is to represent respect and appreciation for our nation’s firefighters. The blade on the Delica is premium stainless steel from Seki-City Japan 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 Thin Red Line has lightweight, skeletonized, stainless steel liners that have been accented with bright red lining. The handle 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, tip-down, left, or right carry.
