These clever credit card sized knives are a perfect addition to your purse or wallet. Need to cut cardboard boxes but don't want to carry a full-blown pocket knife? Feeling stabby? Just kidding. Don't stab people. No seriously, don't do that. Also, don't try to take them on a plane because TSA will find them, but hey, if they do who cares because they're inexpensive. These knives also make great gifts and stocking stuffers for people who like interesting stuff.
