Abstract
1. A circular saw with riving knives (20) comprising a saw blade (17) seated on a link (15) for pivotal movement relative to the supporting surface (12) of a supporting plate (11), and a riving knife (20) seated on a riving knife carrier (19) for pivotal movement about the axis (18) of the saw blade (17), which riving knife (20) can be forcedly pivoted about the said axis (18) through a follower mechanism (15, 23, 25 and 26) taking the form of a four-bar linkage, the connecting rod (23) of the said four-bar linkage being formed by one arm of the riving knife carrier (19) and its first link being formed by a link (15), characterized in that the connecting bar (23) can be moved independently of the link (15) by an external force acting upon the riving knife (20).
