Abstract: A cutting device includes, at least one stack of cutting elements attached to a cutter surface having, a first element and a second element attached to the cutter surface, and a third element attached to the first element and the second element, the three elements being sized and shaped such that prior to attachment to the cutter surface the three elements are restable in a stable manner on the cutter surface due to gravity alone such that a plane-defined-surface defined by one of the two planes of a modified gilmoid of the third element positioned further from the cutter surface is oriented at an angle of about 35 to 55 degrees relative to the cutter surface.

Abstract: Cutting elements for downhole cutting tools comprise a top surface having a cutting surface portion and a cutting profile disposed across the top surface. The cutting elements comprise first and second longitudinal side surfaces and first and second lateral side surfaces, each having a respective cross-section. The cutting profile can be disposed on the cutting surface either asymmetrically or symmetrically. Asymmetrical disposition permits two cutting elements to be arranged facing each other to cover a center point of a cutting tool. The cutting edge of asymmetrical or symmetrically disposed cutting profiles can have a shape that facilitates self-sharpening during cutting.
