The Spyderco C192TIBLP PITS Folder Slip Joint Knife Blue Titanium Satin Plain Edge. The PITS (Pie in the Sky) Folder is based on Mike Read's popular non-locking folder, which has been designed to comply with British knife laws. It has a full-flat ground N690Co steel clip point blade and precision-machined skeletonized titanium handle that aids in providing texture for grip. In addition, the handle features integral split spring arms to form the knife's unique slip-joint mechanism. Mike Read designed this knife to be a tough, hard-use folder and the combination of the lower blade guard with the integral spring act to prevent unintended closure. The PITS Folder includes Spyderco's deep carry wire clip for reversible tip-up carry.
