Abstract
A dual blade retractable tool is provided. The tool has a round tubular housing and a one-piece injection molded slide block structure. The housing has a longitudinally extending control slot and two ends with blade extension openings, one major and one minor. The one-piece structure has a major blade and a minor blade, each carried by a support. Each blade projects through the corresponding blade extension opening. One support is attached to a leaf spring cantilevered at the other end. The spring carries a control button, which projects through and moves within the slot, and a locking pin, which extends beyond the spring perpendicular to the control slot. Depressions in the tube engage and dis-engage with the locking pin as the button is pressed and moved.
