Brush and weed cutter blade

Abstract

A cutter blade has a body portion with a central attaching hole for removable attachment to an output end of a powered tool. The blade has a pair of oppositely extending ends with beveled cutting edges on their leading edges. The body and end portions of the blade are curved upwardly for increasing the efficiency in the cutting operation of the blade. It is preferred that the radius of curvature of the blade be approximately 30 inches and that the sharpening bevels on the leading edges extend from a point adjacent the mid point of the blade to the tips of the blade. The cutting edges are progressively narrower from the mid point to the tips for increased cutting efficiency and blade strength. The cutter blade also has clearance bevels on the lower surface thereof at the trailing edges of the end portions. These clearance bevels extend from an inner area of the body portion short of the mid point of the blade to the respective tips.
