The term bi-metal describes the means of manufacture of the saws. The teeth
are made a (very) hard tool steel, and are welded (or sometimes brazed) to
tougher, softer steel that forms the rest of the saw. Saws made entirely of
tool steel are too brittle, and break easily, while a saw made entirely of
tougher steel will wear too quickly. All good quality metal cutting saw
blades these days are bi-metal. I don't have any experience with the Morse
saws, but can say that the Starretts are very good.
