This is a replacement handle for all Kershaw Blade Trader knives. It fits all the Deluxe Blade Trader blades as well as the Alaskan Blade Trader Blades. Simple to use, just lift up the Quik-Lock, remove the first blade or tool, replace it with the second, then close the Quik-Lock. Each Blade Trader handle is engineered with attention to function and form. Even after years of constant use, the patented Quik-Lock mechanism will securely hold each blade in place. To make the job more comfortable, the non-slip Blade Trader handle is ergonomically designed to reduce hand fatigue.
