The present invention provides a generally circular cutting blade suitable for use in conventional circular saws or equivalent power tools such as table saws and the like. The cutting blade of the present invention utilizes a pair of angled or concave portions or segments (as viewed from one side of the blade). A first portion is located at the radially outward periphery of the blade and a second portion is disposed radially inwardly therefrom. These first and second angled or concave portions are connected by a relatively flat blade portion that permits the radially outward portion to flex or deflect slightly from side to side as the blade is rotated through a work piece.
