  • Patent number: 5125157
    Abstract: A handle of a knife is provided with a recess for receiving an implement, such as a tool or a toothpick. The recess is between the sideplates of the knife and above a locking bar spring. The implement has a hole for accepting a pin carried by a pivotally mounted arm. When the arm is in a first pivotal position, the pin is in engagement with the implement to hold the implement in the handle recess securely. When the arm is rotated, as by pressure exerted by a user's thumb, the arm is rotated and the pin is lifted from engagement with the implement to allow the implement to be withdrawn from the recess in the handle.

  • Patent number: 4985998
    Abstract: A knife having a foldable blade includes a locking bar which holds the blade in an open position. A release lever is provided on the side of the handle for releasing the locking bar and allowing the blade to be moved to a closed position. The release lever has a laterally exposed portion which is flush with the outer surface of a bolster of the knife and a projection which extends into the recess which receives the blade when the knife is closed. The projection engages the bottom surface of the locking bar and urges it upward when the laterally exposed portion is depressed.
