The Breaker is a conveniently designed cycling multi tool. It's essentially an upgraded version of the Nutter, a stainless steel device that blends a multi-bit cycling multi tool and tire level. Specifically, the Nutter now includes a chain-break tool.
The Breaker is fitted with a special receptacle that can hold on to a number of interchangeable pieces. These include five different sizes of hex tools, a Philips head screwdriver, flat head screwdriver, a T25 torx bit and a magnetic tool bit extender.
The developers of the Breaker cycling multi tool are currently running a Kickstarter campaign to raise funds for their invention. A pledge of $55 will get you a basic Breaker if and when the campaign hits its fundraising goal, while $75 will get you a Breaker and socket set.
