Once upon a time I had a manually operated 'circular' saw designed
especially for cutting through floorboards. It consisted of a circular
blade attached to a handle (so that only some 90 deg or so of the
blade could cut) mounted in a base upon which you knelt to apply
pressure upon the floorboard. A setscrew sort of device limited the
cutting depth.
Of course the blade could be reset when it got blunt to present a
fresh set of teeth to the work.
Pretty slow, but very useful, and being manual it was environmentally
friendly. It's a shame that everybody seems to insist on power tools
these days.
