A saw apparatus comprises an operatable saw blade and a holding arm for gripping an object to be sawed, plus means for moving the saw blade and holding arm together to cause the saw blade to engage the object for sawing under controlled-pressure conditions. The saw blade is carried by strain gauge means, the strain gauge means being part of electronic means for sensing the load of the operatable saw blade on the strain gauge means. Thus, pressure of the object for sawing against the top of the saw blade causes an increase in the load sensed by the strain gauge. The electronic signal generated thereby may be used in a feedback system to control the pressure of the workpiece against the saw blade.
