Re: Chain Breaker alternative
Hugh Made says it clearly
...but a punch and hammer works fine. I never grind the end of a pin. If you do, it may not hold well if you try to reuse it....which often happens. To use a punch, just put the link up on an old small socket so the pins has somewhere to go, put the punch on the pin, and drive it out.
Spad here I grind to shorten a chain.
