A circular saw 30 includes a housing 32, a fixed upper guard 34, a movable lower guard 36 and a shoe 38. A saw motor 48 is selectively operated to rotate a circular saw blade 54 to facilitate the formation of a selective cut or kerf into a workpiece 57 under the control of an operator. A forward end 126, and a wing wall 138, of the upper guard 34 form an enclosed chamber 122 which is placed in close proximity with an adjacent surface 46 of the shoe 38 to essentially preclude chips from discharging through a slight space 39 therebetween. A trailing peripheral portion 148 of the upper guard 34 is formed with an inner radial path for receiving the lower guard 36 within the upper guard, and an outer radial path for management and directing of chips to a rear end 130 of the upper guard for discharging of the chips. A pair of stripes 102 and 104, and a sight window 90, are located on a forward portion of the surface 46 of the shoe 38 to assist an operator of the saw 30 in the accurate formation of the kerf.
