  • Patent number: 8893427
    Abstract: An inexpensive fishhook and a method for manufacturing the same whereby a piece of bait can be put as far as an end part of the chimoto side. An upper part of a shank (2) of a fishhook (1) is hit to form a flat surface (3) thereon, and a hole (4) penetrating through the flat surface (3) is formed at two points with a vertical interval therebetween. A part of the shank (2) is cut transversely across an upper hole (4a) of the holes to thereby form, at the upper part of the shank (2), a hole (4b) through which a fishing line (5) is passed and tied, and two upward protrusions (7) enabling a piece of bait to be engaged therewith and being capable of preventing the fastened fish line from being displaced from the upper part of the shank.
