  • Manual table saw and blade therefor
    Patent number: 8544372
    Abstract: A cutting device (10) includes a sled (12) guided on a base (14) for reciprocating linear movement along a blade (20) that is supported on the base below the sled and includes an inclined working edge (28) projecting beyond the sled. The sled is manually movable while the blade is held stationary, so that a workpiece supported on the sled is conveyed against and along the working edge for cutting the workpiece. Mechanisms for adjusting the blade height, inclination angle, and bevel angle are also disclosed. Novel saw blades are also disclosed, and preferably include a blade extension extending from the working edge beyond the maximum travel of the sled. The blade extension may remain in the kerf at the end of a cutting stroke, preventing the blade from jamming against the workpiece upon a return stroke and may also provide an unobstructed means by which to gage blade angle relative to the sled.
