Ive always used the direct drive circular saws. I was watching a guy
building a home and he had a rather large saw which was a lot heavier
than my saws and a lot longer. His was a Skil brand. I asked him about
it and he said it's a worm gear saw, which is why it's larger and
heavier.


So if there is an advantage, what is it?

Yes there is an advantage in framing wood construction. Used all day,
every day, for months or years. A DIY circ saw, direct drive is not
the better tool in routine construction needs. We used one to frame my
patio cover.

I read sometime back that on the west coast the majority of framers use
worm drive, much less on the east coast. We tend to use what we grow up
with I guess.

The circular saw worm grows originally in the Sagarro cactus, and its
range spreads with time, but slowly. Only a mile or two a year. If
worms are found in east coast circular saws it's because vegetables
traveling by freight train got infected and they got to the east coast
that way.
