Because the best knife is the one that's always on you.
There's seriously nothing more frustrating than finding yourself in a situation where you need a knife but you don't have one.
However, if you were to have the Gerber Zip Blade, you probably won't be unprepared every again. Although small enough to hook onto your zipper, this blade is mighty and perfect for many EDC uses, and it's only $8.79.
Don't be fooled by this blade's size. It's made of tough stainless steel and can tackle any small project you've got for it. You can cut twine or slice open a box with this quick clip blade while also carrying it around with you everywhere.
Should you rely on this knife for everything? Probably not. Would you be silly to not give this go-anywhere fine edge utility blade a chance? Definitely.
