Garrett Wade Brass Capsule Multi-Tool
Unscrew it, screw it in, and get your screw on with the Garrett Wade Brass Capsule Multi-Tool. And if you don't like screwing in the 4 different ways the capsule offers - flat head screwdriver, phillips head screwdriver, gimlet / drill bit, and corkscrew - then get hooked instead on its pull hook knife.
The Brass Capsule Multi-Tool design is based on a vintage version Garrett Wade saw at a London flea market years ago. This updated version is made of solid brass, with 5 tools of assorted steels. The knurled center joint of the capsule unscrews to provide tool access, and a reinforced brass slot secures your selection so you can screw the two halves back together, and use the capsule as a handle.
The Brass Capsule Multi-Tool is a little over 3" long and weighs less than 3 ounces.
