Abstract
Cutting instruments and related methods are disclosed herein in which the diameter of the retrograde cutting blade can be adjusted to any of a plurality of diameter settings, allowing the same instrument to be used to form holes of different diameters. The limit diameter can be preset such that, during the cutting operation, the user need not be concerned with selecting the appropriate diameter, but rather can simply deploy the cutting blade until the preset limit is reached. Cutting instruments are also disclosed in which the retrograde cutting blade is distinct from the forward drilling tip and protected within a cavity formed in the body of the instrument when not in use, as are instruments in which the user is given visual and/or tactile feedback to confirm desired positioning of the cutting blade.
