The Zing features the Flipper ambidextrous opening system for smooth and easy opening.
This premium quality blade is paired with a sturdy handle of injection-molded Polyimide® that provides strength, light weight, and a secure grip in most any environmental conditions. A locking stainless-steel liner ensures the blade locks securely.
I should add that I now carry a pair of Kershaw Junkyard Dog II's with composite blades. Kershaw's customer service was my first consideration when making the purchase decision.
I love my Tenacious. I carry it for EDC chores and still carry my Gerber 06 Auto for self defense and defense against gun grabs. Tenacious hand down can not be beat for the price. IMHO.
