An accumulated wear amount calculation section calculates a wear amount of a blade edge of a punch and a wear amount of a blade edge of a die when a tool set of the punch and the die has processed a sheet metal once. The accumulated wear amount calculation section calculates an accumulated wear amount of the blade edge of the punch and an accumulated wear amount of the blade edge of the die by accumulating wear amounts of respective times when the tool set has processed the sheet metal multiple times. A tool management information managing section manages a state of the blade edge of each punch and each die by causing a tool management information storage section to store tool management information associating a tool identification code given to each punch and each die with the accumulated wear amounts calculated by the accumulated wear amount calculation section.

A surgical shaving instrument (1) comprises a main body (2), a hollow elongate shaft (4) extending from the main body (2). The elongate shaft (4) defines an elongate inner open volume through the shaft. A tip portion (18) extends from the distal end region of the elongate shaft (4). A driveshaft extends through the elongate shaft (4) from the main body (2) to the distal end region of the elongate shaft (4). A cutter head (12) is attached to the driveshaft and located in the tip portion (10), the cutter head (12) extends at least partially out of the tip portion (18). The aperture of the tip portion (18) is defined by an inner edge, and a portion of the inner edge defines a fixed shaver blade (40) for the instrument, the fixed shaver blade (40) having a cutting angle which is substantially constant along the inner edge.
