ABSTRACT:
The invention relates to a fishing sinker of iron material that is either cylindrical, with an elongate or tapered construction having a through hole for passing therethrough a fishing line, or mostly spherical with a slit for holding a fishing line, and a method of making a fishing sinker of iron material without the use of die casting comprising the steps of: (a) cutting on a punching tool an iron bar to form an iron blank of a predetermined length; (b) transferring the iron blank to a second position on the punching tool, whereon the iron blank is punched a straight hole at one end thereof or respectively at both ends thereof; (c) punching to enlarge the straight hole; (d) punching a through hole along a longitudinal axis of the iron blank so that the iron blank becomes a cylindrical blank; and (e) forging the cylindrical blank on the punching tool so that the cylindrical blank is stretched out to form a fishing sinker having therein a through hole to receive a fishing line.
