Abstract: A cutting instrument can include a blade body having at least one face and a cutting wedge. The cutting wedge can include a leading edge and one or more cutting fasciae extending from the at least one face and defining at least a portion of the leading edge. The one or more cutting fasciae can have a surface roughness comprising one or more of: (1) a measured maximum height (St) of 1.5 ?m or less with a standard deviation of 0.4 ?m or less within a measurement area of 16,641 square microns on at least the portion of the one or more cutting fasciae, or (2) a measured arithmetic mean peak curvature (Spc) of 150 mm?1 or less with a standard deviation of 30 mm?1 or less within the measurement area of 16,641 square microns on the at least the portion of the one or more cutting fasciae. Other embodiments are described.

Abstract: Various embodiments for an improved cutting instrument defining one or more angularly-oriented cutting fasciae having uniform cutting surfaces with reduced surface topography are disclosed.

Abstract: A cutting instrument includes a cutting wedge. The cutting wedge can include a leading edge and one or more cutting fasciae terminating at the leading edge. The one or more cutting fasciae can include an approximately concave recess. Other embodiments are disclosed.
