Abstract
Abstract Metal alloys in an amorphous state are employed in the fabrication of cutting implements such as razor blades or knives. The implement may be formed from the amorphous metal or a coating of the amorphous metal may be applied. Such products may be formed from a ribbon of the amorphous metal alloy which has been prepared by quenching the molten metal or by coating the amorphous metal alloy on a suitable substrate such as by a sputtering procedure or vapor, chemical or electro-deposition of the alloy on the substrate.
