doing it with a dremal and a punch won't fit in your tool bag, but it doesn't put any extra stress on the chain because you lock it in the vice with the link your removing. don't take much preassure to hold it ither, no more than a chain breaker takes, and it's 1/2 the hassle.... but yes if it snaps on the road, your left with 2 options, pedal home or use a breaker and master link and fix it
