Abstract: A tool pouch, tool bag, utility pouch, or similar, comprising one or more individual tool pouches, used by tradesmen in difficult and/or dangerous environments where it would be convenient and preferred for safety reasons for the tool pouches to remain closed or remain open without manual intervention. Tool pouches within a tool pouch are configured with bi-stable hinges in which an over-center cam-spring arrangement alternatively maintains either a fully-closed or a fully-open configuration until an intentional opening or closing action by a user. Individual tool pouches within a tool pouch may be opened or closed independently of the open or closed positions of other tool pouches.

Abstract: A tool pouch, utility pouch, or the like, used on traditional tool belts with spring hinged closure device in the open position forces the mouth of the tool pouch into a fully open position creating greater access to the contents of the tool pouch. When the mouth of the tool pouch is pressed into a closed position, it secures the content of the tool pouch therein.

Abstract: A utility knife includes a blade holder that permits quick and easy removal and replacement of the utility knife blade. The utility knife includes a sleeve which receives the blade. The upper portion of the sleeve includes a pivoting arm which engages indentations in the trapezoidal utility knife blade holding the blade in position. By pressing down on one end of the arm, the arm disengages the trapezoidal blade allowing it to be removed and replaced.
