Though named the Breaker, this bicycle chain breaker by Full Windsor has plenty of additional functions. "It features a tool bit extender that can be used as a handle, giving you the functionality of a workshop chain breaker in a conveniently compact multi tool," writes manufacturer Full Windsor. "A magnetic tool bit slot located at the end of the tool allows it to be used like a screwdriver as well. The tool magnetically houses 2 tool bits inside its structure."

The tool comes with seven bits (PH2, T25, and hex tool bits in 3, 4, 5, 6 and 8mm). Additionally, it's got a tire lever, a spoke key, and (of course) a bottle opener.

The Breaker comes with a pouch made from leather and a recycled inner tube.

Made of stainless steel, it's a bit weighty at 8.5 ounces all-in, but rings in at a reasonable $35. Astronaut not included.
