  • Publication number: 20030038195
    Abstract: A carrier for a rasp that serves to support the rasp when it is in use and store the rasp when it is not being used. The rasp carrier includes a bottom, two side walls, a back wall, and a tab positioned on the back wall. To support the rasp, the rasp is positioned atop the carrier. The side edges of the rasp fit over the side walls of the carrier to prevent lateral movement of the rasp relative to the carrier. A mounting hole on the rasp engages the tab on the rasp carrier to prevent linear movement of the rasp along the carrier. To store the rasp, the rasp is removed from the top of the carrier and slid between the side walls of the carrier.
