Abstract
A blade for a cutting instrument includes a handle, a body, and at least three cutting edges along the body. The body has first and second sides extending along a longitudinal center axis. The body has a proximal end at the handle and a distal tip remote from the handle. The at least three cutting edges are oriented at corresponding angles with respect to the longitudinal center axis and are asymmetrically distributed with respect to the longitudinal center axis.

A blade for a cutting instrument, comprising:
- a handle;
- a body having first and second sides extending along a longitudinal center axis, the body having a proximal end at the handle and a distal tip remote from the handle;
- and
- at least three cutting edges along the body oriented at corresponding angles with respect to the longitudinal center axis, the at least three cutting edges asymmetrically distributed with respect to the longitudinal center axis.
A blade for a cutting instrument, comprising:
- a handle;
- a body having first and second sides extending along a longitudinal center axis, the body having a proximal end at the handle and a distal tip remote from the handle;
- opposite first and second non-cutting edges along the body extending from the proximal end between the first and second sides, the first and second non-cutting edges oriented parallel to the longitudinal center axis;
- and
- at least first, second, and third cutting edges along the body oriented at corresponding angles with respect to the longitudinal center axis, wherein the first cutting edge extends from the first non-cutting edge, the third cutting edge extends from the second non-cutting edge, and the at least first, second, and third cutting edges are asymmetrically distributed with respect to the longitudinal center axis.
