The handle grip part (2) of the scalpel-blade holder (1) has three side surfaces so that the cross-section produces a triangular envelope. At least one of the side surfaces has a tactile recognition mark in the form of a protuberance (5) or recess. The holder has an end part (3) tapering from the handle part. The blade (7) is fixed by means of a hole running axially through the end part. |
