摘要： Circular saws having a blade that moves relative to a stationary base structure during operative use of the circular saws to cut a workpiece and methods of detecting a kickback condition of such circular saws. The circular saws include a base structure, a user-actuated assembly, an attachment structure, and a controller. The attachment structure is configured to permit constrained relative motion between the base structure and the user-actuated assembly in a motion direction and during operative use of the circular saw to cut the workpiece. A motion sensor is configured to generate a motion signal indicative of motion of the user-actuated assembly along the motion direction. The controller is programmed to initiate a kickback response of the circular saw responsive to the motion signal being indicative of a kickback condition of the circular saw.
