Another question from an innocent who's been away from metalwork
for some time. Bi-metal obviously means two metals in the blade. One
on the edge and another for the main body? Better?
You got it in one. Hard edge, soft(and flexible) back. My dad used
to gas on and on about Atkins Silver Steel blades that he had when he
was a kid working in the sulky factory and how they'd last forever and
the new bimetal blades didn't last as long. They were apparently a
full hardened blade because he said they'd shatter if you happened to
twist the blade just a little in the cut. It's harder to do that with
a bimetal blade. I think his problem with bimetal blades was that the
electrical contractors he worked for bought the cheapest junk they
could get to pass out to the workers. Buy some decent US-made ones,
match the tooth pitch with the work and you'll have no problems.
