ABSTRACT:
Improvements are provided in the structures of cutting tools and methods for producing such tools. The tool structures include providing a select portion or portions of a cutting tool, such as one or more portions adjacent a cutting or forming portion or edge or plurality of edges of a tool, of amorphous or non-crystalline metal or metal alloy having strength and wear characteristics which are superior to those of conventional metals and alloys which are crystalline in structure. Such amorphous metal may be formed in situ along the cutting edge portion of a cutting tool or blade by intense radiation beam scanning or may be formed of deposited or otherwise secured amorphous metal strip.
