Claim 19:
20. An electrosurgical device for cutting tissue, comprising:
a body portion; and
a tool portion extending distally from the body portion, the tool portion defining a longitudinal axis, the tool portion including:
a return lead configured to electrically couple to an electrosurgical energy source, the return lead including:
a distal surface defining an acute angle with respect to the longitudinal axis of the tool portion;
a planar surface extending from the distal surface of the return lead to a distal end of the body portion; and
a nose portion extending distal to the distal surface of the return lead and configured to engage the tissue;

a pair of electrical insulators extending distally from the distal surface of the return lead parallel to the longitudinal axis of the tool portion; and
an active lead extending through the pair of electrical insulators and configured to electrically couple to the electrosurgical energy source for cutting the tissue, the active lead having a surface area less than a surface area of the return lead.
