Abstract
A retractable 'ball-pen' like tool/scalpel, provided with a latch mechanism, is automatically retracted when not in use by pushing the latch mechanism and is extended when in use by pushing a tool/blade support member of the tool/scalpel. An enlarged section of the latch mechanism is matched and engaged with an enlarged slot portion of the tool/blade support member when the tool/blade support member is pushed to an operative position wherein a tool/blade is exposed from a sheath member. The enlarged section of the latch mechanism is pushed transversely and disengaged with the enlarged slot portion of the tool/blade support member, the tool/blade support member is forced back to an inoperative position wherein the tool/scalpel is retracted into the sheath member.
