ABSTRACT:
Manual tool used for trimming mold flash and protuberances from a tire has a handle with ends which are slotted to receive mounting flanges of a undulated sheet metal blade. The blade is so folded that its undulations comprise closely spaced ridges which extend from front to rear, are open on their underside and are united by narrow intervening webs. The underside of the lead edge of the blade is sloped along an arc and/or angle providing the blade with recesses in said leading edge between the ridges. The recesses have sharp cutting edges which cut entering flash close to the tire surface, the open under side of the ridges on either side of the webs providing clearance for missed flash and trimmings so that the tool blade is not raised off the tire surface in use of the tool.
