Also Martin, crosscut and rip saws are sharpened differently. Rip saw
teeth are sharpened straight across and act like little chisels.
Crosscut teeth are sharpened at an angle and act like little knives.

There are, of course, the specialty "no set on a side" dudes for things
like trimming dowels flush and the like, but the general truth is indeed

strokes get the barrel of the blade in the kerf with no clearance --
which of course, was the "trick" w/ the 120; the body was thinner than
the teeth to provide, if you will, "reverse set".
