For hardness, corrosion resistance and wear resistance, the Kershaw Zing knife Model 1735 features a high-carbon Sandvik 14C28N stainless-steel blade, and grooves that are 3D machined in an striated pattern. Kershaw pairs it with a sturdy handle of injection-molded Polyimide in classic black. A locking liner ensures the blade locks safely. Open the Zing one-handed with the built-in thumb stud or use Kershaw's ambidextrous Flipper.
