I've got an 18volt DeWalt reciprocating saw and I'm going to be cutting some
steel bolts (mostly 3/8") tomorrow. I plan on starting my day by picking up
a few blades for the job.

I was just wondering, what would be the best blade for the job? Work is
going to be done in tight quarters, and the blade is going to slide between
some parts of the assembly.

So I figure that a thin (maybe .035"), 6 inch long, bimetal blade with 14 to
18 teeth per inch should do the trick
