Abstract: A cast removal device having a blade assembly driven by a cordless tool is provided. Mirror image opposing first and second blade members having cutting edges along a lower inner edge thereof are disposed in parallel with a third blade member sandwiched in between. Each of the first and second blade members has a first planar surface and a second planar surface, a first longitudinal edge and a second longitudinal edge, first and second ends, and an opening disposed proximal to a midpoint. The third blade member has a first planar surface and a second planar surface, a first longitudinal edge and a second longitudinal edge, first and second ends, and a pivot point disposed proximal to a midpoint thereof. Means for rotatably connecting the first, second and third blade members at the pivot points thereof are provided as well as means for securing the first and second blade members together to prevent rotation with respect to one another.
