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.

A saw blade, comprising:
- a blade body which defines a first side surface and a second side surface, wherein (i) said blade body has a multiplicity of discrete dimples formed on at least one of said side surfaces, (ii) each of said multiplicity of dimples defines a perimeter which is spaced apart from all edges of said blade body, (iii) each of said multiplicity of dimples includes a ridge which is located at said perimeter, (iv) at least a portion of said ridge extends above said side surface of said blade body in which said dimple is formed, and (v) no opening exists which extends from said first side surface to said second side surface through any of said multiplicity of dimples;
- and
- a plurality of cutting teeth extending from said blade body,
- wherein said ridge extends around the entire perimeter of said dimple.
