Abstract
A double sided hack-saw blade is formed from a thin elongated metal strip having opposed longitudinal side edges respectively provided with first and second parallel saw tooth cutting edges. The blade is designed for reversible securement to a hack-saw handle to allow alternative use of the first and second cutting edges. The cutting edges may be formed with different tooth pitches to allow a single blade to be utilized for various diverse cutting operations. A removable cover for engagement with one of the cutting edges when not in use is formed from a three sided member having a rectangular channel dimensional for frictional engagement with the hack-saw blade. The cover includes a lubricating wick to lubricate the cutting edge and also provides protection to a user.
