To enable using of a right angle-cutting jig by making a saw a double- edged or single-edged saw with a change edge barrel and a hand-held saw capable of halfway stooping of cut.

In a hand-held saw, a saw plate 3 is fixed to a slender saw plate holding member 2 fixed integrally to a grip 1 by both ends. The saw plate 3 is movable in the cross direction by loosening the fixing, and by arranging an edge 3a and the contact surface 2a of the saw plate holding member 2 in parallel and fastening/fixing the saw plate 3 to be a prescribed size for stop cutting, a hand-held saw capable of halfway stopping of cut in a desired size is prepared. A clearance is formed between the member 2 and the saw plate 3 and engaged with a known right angle-cutting jig.
