The Gerber Shard is a lightweight multitool. This key-sized, flight friendly, shard of nitride coated titanium features a bottle opener, philips screwdriver, two sizes of flathead screwdriver, a wire-stripper, nail-puller, and it’s a mini-crowbar. It’s also pretty much indestructible. I’ve personally had this on my keyring and it’s been one of the most useful things I’ve carried.
