We’ve seen other pocket multi-tools that fit over a key, but many of them had a knife blade and were a concern for traveling by plane. This True Utility TU247 KeyTool MultiTool doesn’t have a knife blade. Instead it has: a bottle opener, nail file, thread cutter, three screwdrivers, and tweezers. The tweezers require you to remove the key, but the other tools can be used by just sliding it around on the key. It’s made of stainless steel and measures 2″ X 0.8″ X 0.1″. It comes with a quick-release clip for your keychain. The True Utility TU247 KeyTool MultiTool is $9.52 from Amazon.
