Introduced in 1990, the Delica was the first its kind on the market. The folder opened up the knife market to lightweight performance, one-hand opening pocket knives that just about everyone could afford. Refinement has been ongoing and countinual with tweaked ergonomics and refined blade steels. The new Delica 4 has screw construction making cleaning and adjusting easier. The VG-10 blades are flat saber-ground with a stronger tip and larger 13mm opening hole. The spine has slip resistant jimping and a David Boye Dent locking mechanism. Phosphor bronze washers smooth out the open/close action. Fiberglass reinforced nylon handles come molded with Bi-Directional Texturing for preferred traction and improved ergonomics. Four-position pocket clip that supports all possible carry combinations.
