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.
