Claim 18:
19. A cutting tool comprising a longitudinal axis and a blade portion forming a distal end of the cutting tool, the blade portion comprising:
a first grind surface;
a second grind surface, wherein the first grind surface and the second together define
a knife edge;
a tip that is a distal-most point of the cutting tool, wherein the knife edges extends in a straight line between the tip and
a choil;
a first chamfer surface that intersects the first grind surface;
a second chamfer surface that intersects the second grind surface; and
a spine section disposed between at least a portion of the first chamfer surface and at least a portion of the second chamfer surface;
wherein the first chamfer surface and the second chamfer surface are entirely disposed within a height footprint of the knife edge such that the choil is more proximal than the proximal-most portion of the first chamfer surface and the second chamfer surface and the tip is more distal than the distal-most portion of the first chamfer surface and the second chamfer surface.
