ABSTRACT OF THE DISCLOSURE A strip-saw blade formed as a strip of metal extending along a blade plane has a front edge portion formed with a row of forwardly directed teeth and a rear edge portion. Measured perpendicular to the blade plane the rear edge portion is sub- stantially thicker than the front edge portion. In addition the blade is symmetrical to the blade plane and the blade is formed between the toothed front edge portion and the rear edge portion with a transition region having oppositely outwardly directed flank surfaces lying inward of respective planes tangenting the respective rear and front edge portions. These transition regions can have a height equal to three times the tooth height. In fact the transition regions can be hollow ground so that they do not contact the workpiece at all.
