A cross-recess screwdriver sharpening assembly for sharpening a cross-recess screwdriver includes a housing that has a sharpening aperture. A plurality of grinding wheels is rotatably mounted within the housing. Each of the grinding wheels is arranged to define a grinding space. A plurality of sleeves is included wherein each of the sleeves is removably extendable into the interior of the housing to have the cross-recess screwdriver positioned therethrough such that the cross-recess screwdriver extends into the housing. The sharpening aperture receives one of the sleeves therethrough and is centrally aligned with the grinding space such that the cross-recess screwdriver is extendable into the grinding space to sharpen the cross-recess screwdriver. A drive is mounted in the housing and mechanically coupled to each of the grinding wheels. The drive is turned on to rotate each of the grinding wheels.

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.
