The tool has a body portion, a handle portion and a stop portion, and is used to facilitate inserting the inner cutter into the outer cutter without damaging the hair shearing edges. In a shaver having cutters with hair shearing teeth; when inserting the inner cutter into the outer cutter the tool is held against the inner cutter with one side of the body portion resting on the toothed wall of the inner cutter, and with the stop portion urged against an end of the inner cutter. After partial insertion, the handle portion of the tool is grasped to thrust the stop portion toward the outer cutter to insert the tool's body portion into the outer cutter along with the inner cutter.
