The Gerber GDC Zip Blade is an ultra-compact Gerber knife that can always be conveniently attached to the zipper of a jacket or bag. A quick-release clip allows for easy removal of the knife with just one hand. The Gerber GDC Zip Blade is small enough to fit in the palm of your hand and sharp enough to open tough plastic packaging. A safety lock mechanism secures the blade in the open position, allowing you to cut safely and efficiently.
