Combination tool
A combination tool is described that has a housing that includes a first side and an opposed second side, a third side and an opposed fourth side. The sides connect together to define the housing. The housing includes a first end portion and an opposed second end portion that define a longitudinal axis. The combination tool includes a razor mechanism that is connected to the housing. The razor mechanism receives and moves a cutting blade between a first position in the cavity and a second position wherein the cutting blade extends through the housing. The housing defines a channel that includes a floor, a first sidewall and a second sidewall. The first sidewall and the second sidewall have first edges that are connected to the floor and second edges that connect to the first side of the housing. The first sidewall includes a first slot and the second sidewall includes an opposed second slot. The first slot and second slot are positioned in fixed spaced relation from the floor and the second edge. The slots are configured to receive a rasp. The slots are positioned to recess a cutting surface of the rasp in the channel such that at least a portion of the sidewalls extend between the cutting surface and the second edges. A claw is defined in the housing that includes a first tong and a second tong. The claw extracts fasteners from soft materials.

Convex rasp
An improved concave rasp that can be used to smooth any concave surface, such as under a hoof, having a handle approximately perpendicularly affixed at about the middle of a rasp that is convex both along its length and in cross section. The underside of the rasp has a rounded end, thus being suitable for applying pressure there against. Another embodiment of the invention is an improved tooth design, comprising a tooth blade, rather than individual teeth, thus providing much increased biting edge with increased durability.

Foam rasp
InactiveUS7748933B1Eliminate the effects ofEasy to disassembleBuilding constructionsFiling/rasping toolsRaspEngineering
A rasp that has a mounting plate with a number of debris vent ports formed in it. The debris vent ports are formed to allow dust and debris to escape, thereby eliminating a hydroplaning effect on the abrasive surfaces while using the rasp, as well as making the tool lighter. A number of sharp pointed screws are screwed into the plate so that the points extend below the base of the plate. The screw tips become the abrasive rasping surface. The screws can be turned in or out to raise or lower the tips, to change the amount of rasping action from fine to aggressive. The screws can also be easily removed when they become worn so that the abrasive surface is always uniform and fresh. Finally, unlike the other tools, the screws can be removed to clean the base of the plate thoroughly to remove dried or caked mud.
