ABSTRACT:
A series of apertures are formed in a blade of a circular saw which define a plurality of the strips interconnecting the toothed annular peripheral portion and the inside portion of the blade.

The width of the peripheral portion is 10-30% of the diameter of the blade and the length of the flexible part of the strips is at least 10% of the diameter of the blade. The flexibility, defined by the formula
