Trying to put the sheet metal roof on my camper. It has to be cut to
size with tin snips giving edges that could take your arm off. The
sabre saw does an even worse job. It'll be ok in the end but I hate
this stuff.
Boat building was much more fun..

Probably circular saw blades that will do a clean cut.
Not sure, as I never did metal with one, but have done brick/concrete.
Billy Mays shilled something called the Dualsaw, with 2 circular
blades counter-rotating.
But you should be done with the snips by now, so you saved some money.
