Don't let its size fool you, the Gerber Shard keychain tool is the perfect companion when you want just the basics. With a shape of its own, the Shard has seven useful functions: small flat driver, medium flat driver, cross driver, pry bar, wire stripper, lanyard hole, and bottle opener. It is light enough to carry on your keychain, but tough and durable enough for everyday use. The Shard is made of stainless steel with a titanium coating, and it measures 2.75 inches. It's backed by a limited lifetime warranty.
