ABSTRACT:
A retractable "ball-pen" like tool/scalpel having 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. The latch mechanism is engaged with 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 latch mechanism is pushed transversely and disengaged with the tool/blade support member whereby the tool/scalpel is retracted into the sheath member. A key member having a post is mounted on a back end of the sheath member. The post and the latch mechanism prevent the key member from falling out of the back end of the sheath member. Almost all the parts of the tool/scalpel can be made of plastic materials.
