Claim Text:
1. A bone cutter, which comprises: a) a first sidewall comprising a first inner surface providing a first lumen extending along a longitudinal axis from a first sidewall proximal portion to a first sidewall distal portion having a first sidewall distal end residing along a first imaginary plane; b) a second sidewall comprising a second inner surface spaced from a second outer surface by a second sidewall thickness to thereby provide a second lumen extending along the longitudinal axis from a second sidewall proximal portion to a second sidewall distal portion having a second sidewall distal end residing along a second imaginary plane; c) a plurality of spaced apart distally facing open ended blade enclosures extending radially between the inner surface of the first sidewall and the outer surface of the second sidewall to thereby fixedly join the first and second sidewalls to each other in a co-axial relationship with the outer surface of the second sidewall being radially inside the inner surface of the first sidewall, wherein the second imaginary plane is more proximal along the longitudinal axis than the first imaginary plane to thereby provide an offset; and d) a plurality of cutter blades, each blade having a length extending from a proximal blade portion to a distal blade portion, one of the cutter blades received in a respective one of the blade enclosures so that a cutting surface of each cutter blade extends along the distal blade portion, parallel to the first and second imaginary planes.
