Abstract
A multi-tool assembly with retractable tape measure, with pivotably mounted, straight edge blade arm, fully sheathed razor blade knife, carpenter's square, protractor and a set of 3 screwdrivers integrated into the housing assembly. The straight edge blade arm and integral razor blade knife, protractor and carpenters square, are fully imbedded into the tape measure housing assembly. The straight edge arm can be manually opened or spring powered to open automatically when a release button is activated, allowing the straight edge blade arm to snap open and lock in place like a switchblade. The set of screwdrivers permanently mounted on the back of the housing assembly are held in the open and closed positions by means of friction and/or a clip mechanism between the screwdriver bit and the housing assembly. The blade arm and screwdrivers pivot open individually, allowing each tool to protrude, and be used independently.
