System and apparatus for removing a casted wall from a human appendage includes a strand embedded laterally through the wall at an inner surface thereof and adjacent the human appendage, and a take-up roller for severing the wall by drawing the strand into a cutting angle adjacent the inner surface and then through the wall, and further including a guide exterior of the wall and having a guide surface about which the strand is drawn. The guide surface is disposed substantially away from the cutting angle along the direction of travel of the take-up roller and the guide, whereby the strand is drawn through the wall and it is at a substantially acute angle of less than 60 degrees.
