Cut your own chain to the perfect length with BikeMaster’s compact, heavy-duty chain breaker. It is made of super-strong, forged tool steel and has a folding handle that allows it to fit anywhere. The chain breaker covers the gamut, from 420 to 620 chains and comes with 2 hardened pins in 3.5mm and 4.8mm sizes. The two-stage design first clamps down on the chain, and then guides the pin precisely onto the head of the rivet. Comes with BikeMaster’s lifetime warranty.

Works great and easy to use. Only problem is if you take too many links out it is not the tool to put it back together.
