Abstract
An improved slot for a circular saw blade that reduces thermal cracking that occurs during the use of the blade. The slot extends from the peripheral edge of the blade in a vertical direction toward the center of the blade. It has an initial channel that takes a slight curve as it extends toward the center of the blade, but remains in a substantially vertical orientation until it terminates in a curve that is convex when viewed from the peripheral edge toward the center hole. The curve extends in both directions away from the channel portion. The first curve extends at a length that is longer than the length of the second curve. The curve does not complete a circle, but resembles a circle that has had been snipped at one point and one side hangs down below the other. Each curve terminates in an aperture.
