Flush cut saw

A saw assembly comprising:

• an electric motor subassembly, the electric motor subassembly having a motor adapted to produce rotational movement about a first axis of rotation and a spindle rotatably powered by the electric motor for rotation about a second axis of rotation that is perpendicular to the first axis of rotation;
• a blade mounted on the spindle;
• and
• a blade guard-guide subassembly that encloses the blade, the blade guard-guide subassembly comprising a top main guard-guide and a bottom guard-guide plate, wherein the bottom guard-guide plate is configured to be slidably moveable between two positions, a first position wherein the bottom guard-guide plate fully encloses the blade together with the top main guard-guide and a second position wherein the bottom guard-guide plate is fully retracted independent of the top main guard-guide to expose the bottom portion of the blade;
• wherein the top main guard-guide includes a rail having rail cutouts, and wherein the rail is coupled to a side of the top main guard-guide,
• wherein the bottom guard-guide plate includes rollers guided on the rail;
• wherein in the second position the rollers are partially received in the rail cutouts, a front end of the bottom guard-guide plate is biased against a rear end of the top main guard-guide, and a bottom surface of the bottom guard guide-plate is tilted above a surface to be worked on of a workpiece.
