Squeak

Handle is FRN and engineered for user comfort whether in the hand, with ergonomic handle texturing or in the pocket with a reversible itp up deep pocket wire clip Held in the open position when cutting by a notched joint at the knife's pivot 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.
