摘要： The present invention is directed generally to tools that are made, at least in part, more durable, particularly one or more working surface(s) of the tools. For example, various tools such as trowels, knives, and scrapers may be made having at least a portion of their blades heat treated to make at least their working edges more durable and extend their useful lives. For example, in various embodiments, a putty knife, taping knife, or scraper blade may have at least one working surface or edge that has been at heat treated while an area of the blade where a handle is permanently attached is not heat treated.

摘要： The method for controlling a motor driving a load holds the speed of the output shaft of the motor substantially constant as the torque imposed upon the shaft by the load varies, then regulates the rate of change of the output torque delivered by the motor's output shaft as the motor's speed decreases.

摘要： The method for controlling a motor driving a load holds the speed of the output shaft of the motor substantially constant as the torque imposed upon the shaft by the load varies, then regulates the rate of change of the output torque delivered by the motor's output shaft based on the sensed value of output torque as the motor's speed decreases.
