Can a knife ever be referred to as "adorable?" If it were ever possible, Spyderco's Bug SS Slip Joint Knife might just make the cut. When folded, this little guy measures just 1.6 inches, and features a 1.3-inch plain edge blade.
Tipping the scales at just 0.4 ounces, it's easily the most convenient travel buddy when you need a blade without all the bells and whistles of some other multi-tools. There's no locking mechanism at work here, but resistant pressure at the joint will keep it open when you find yourself needing to cut tiny holes or open tiny letters. [$15, Amazon].
