Sharp enough for everything. Slim enough to come with you. The Exchange-A-Blade family was designed to disappear into your pocket or keychain until you need it. It's novel bolt-action mechanism allows for easy one-handed opening and closing. This is by far the most useful tool I have designed for Gerber and I keep them all over the house, shop, car etc. Having a utility blade in the pocket is incredibly handy and this is the slimmest way to carry one.
