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. 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.
