While we've all resorted to using a key to cut open a box, this keychain tool takes that solution a step further. Its hooked-end cutter easily slices through packing tape, envelopes, cardboard and even clamshell packaging.
For safety, the 1 7/8" blade has a blunted tip and locks in the open position. It also has a 1" curved secondary cutting edge. The blade is stainless steel with a Teflon coating; the key-shaped handle is tough glass-filled nylon with a hole for attaching to a key ring. Convenient to carry, it is only 2 3/4" long when folded and weighs just 0.4 oz (10g).
