Several embodiments are disclosed in which the saw blade has 3,4,5,6,7,8,9, etc., up to 12 teeth. Additionally disclosed are saw blades in which the order of the leading tooth and the trailing teeth are varied, the tips of the teeth form an arc, the leading tooth is formed in a V-shape, the leading tooth has a V-shaped or U-shaped notch in the tip, a cutting removal channel is formed in the gullet of the teeth, and the tips of leading teeth and trailing teeth are configured to conform to a straight-line shape or a shape in the form of the arc of a circle.
