Armchair saw

[Toolmaker51]

There are at least two tooth forms, and amount of set, plus varied handles. One I have like Marv's link, ~8", flexible, flush cut, single edge, no set, knife handle. Dynamite on dowels, barest of need to sand or plane. The other, used less often is ~12" or 14", double edge fine & coarse, more set on coarse, not too flexible, off set handle secured by flat head screws & wing nuts, very cool because that makes it reversible right or left + up or down! Not switched much, but handy as all get out not stuck in a closet, on a ladder, using fine pitch on door jamb, then 2 second story windows. Even harder to work on both sides.
