Spyderco Squeak ~ C154PBK

Produced in Maniago, the Squeak SLIPIT is a Spyderco non-locking one-hand open, clip carry folder called a SLIPIT. It's designed for legally-restricted carry in locales where locking folders are prohibited. 

The blade is ground full-flat and made from Austrian Bohler-Uddeholm's N690Co steel. N690C0 is high-carbon steel with added cobalt for structural uniformity resulting in enhanced edge retention and sharpening receptivity. Textured jimping is machined from the blade's spine and choil for increased slip resistance. 

The Squeak's blade is held in the open position when cutting by a notched-joint at the knife's pivot. When closing the blade, the notch generates resistance functionally similar to traditional slip-joint penknife and performs the additional function of smoothing the motion of the blade opening. Increasing control and comfort Spyderco designers add a deep finger choil, naturally jogging the index finger into a position on the underside of the blade directly below the thumb. Positioning the index finger in this choil blocks the blade from accidental closing when cutting and provides a grip position that allows the user to choke-up closer to the cutting edge for greater dexterity. 

The handle is FRN (fiberglass reinforced nylon) and engineered for user comfort whether in the hand, with ergonomic handle texturing, or in the pocket with a reversible tip-up deep pocket wire clip.
