The Master Craftsman is a five layer Swiss Army Knife which includes a metal saw/file and a wood saw. All five layers have a backside tool. The Master Craftsman is closely related to the Ranger which has a corkscrew instead of a Phillips screwdriver.
This version features an inlaid image of the Space Shuttle. It is sometimes referred to as the Astronaut model. More information on this model can be found on SAKWiki.
