well, i went out and got it. put the blade for metal in, pulled the
trigger, touched the blade to metal and bingobango the blade snapped
right in half.
put another blade in, tried to go at a piece of wood at a slight
angle, pulled the trigger, felt something wrong, stopped, looked at the
blade and twas bent to one side.
maybe it's the blades?
guess i'll go back and get some bimetal ones. see how they do.....
