Abstract: A saw blade includes a blade body which defines a first side surface and a second side surface, wherein (i) the blade body has a multiplicity of discrete dimples formed on at least one of the side surfaces, (ii) the blade body is made of metal, and (iii) each of the multiplicity of dimples is formed by a process which includes the step of deforming the metal so as to create an indentation in the side surface in which the dimple is formed. The saw blade further includes a plurality of cutting teeth extending from an edge of the blade body. Moreover, the deforming step includes the step of deforming the metal with pins on a die plate of a punch press.

Abstract: A method of making a saw blade includes the step of providing a metallic blade body that defines a first side surface and a second side surface. The method further includes the step of providing the metallic material blade body with cutting teeth at an edge thereof. The method also includes the step of forming a plurality of discrete dimples on at least one of the side surfaces. The forming step includes the step of deforming the metallic blade body with pins on a die plate of a punch press so as to create a plurality of indentations in the side surface in which the dimples are formed.

Abstract: A tool having a body with two broad sides and a margin along which a cutting edge extends, and discrete, discontinuous protrusions from at least one of said broad sides, spaced from said cutting edge and from one another. The protrusions can take the form of concave dimples with a ridge on their perimeter or convex dimples with a smooth outermost surface, with or without complementary concave dimples, which preferably, but not necessarily, have ridges on their perimeters.

Abstract: A circular saw blade with improved stability, the blade having a plurality of radial expansion slots, preferably having a "J"-shape. The blades may also have a plurality of arced body slots and may be coated with a "TEFLON" paint mixture.
