  • Method of manufacturing a hacksaw
    Patent number: 7222555
    Abstract: A method for manufacturing a handsaw capable of cutting a glass bottle. The method includes cutting a steel strip to a predetermined length to form a handsaw substrate. A portion of the handsaw substrate, other than a cutter blade forming portion formed on at least one edge of the handsaw substrate in a widthwise direction is masked. A hard abrasive is applied onto the portion of the handsaw substrate other than the masked portion. The handsaw substrate, to which the hard abrasive has been applied, is dipped in an electrolytic solution tank to deposit a metal layer in which the hard abrasive is embedded.
