The greatest, most badass knife in the world is of little use when it’s sitting in a drawer in your home. For a little blade that you can keep on you at all times, check out this Gerber GDC Zip Blade. Since the tiny blade straps right to a zipper, you can have a cutting tool within arm’s reach anytime you need. The clip allows for quick removal, and the body features a frame lock for safe usage. Is it the largest and most effective knife ever made? No, but it won’t collect dust on a shelf because it’s too cumbersome to carry around all the time.
