This 0.68" fine-edge utility blade has enough pluck to strip wire, cut cardboard, and slice through clamshell packaging. Part of Gerber's Daily Carry collection, the Zip Blade also features a quick-release clip for removing the tool quickly and with one hand.
The Zip Blade has a frame lock to keep the knife secure and wobble-free when open, plus a built-in fob for attachment to the zipper of a jacket or bag.
