Claims (1)

[Scope of Claim for Utility Model Registration] 1. Providing continuous or intermittent streak-like protrusions in the axial direction on a wire or similar material used as a fishing hook material, and applying a rotary blade or blade obliquely to the streak-like protrusions,
A manufacturing method in which a fishhook is formed after diagonal unevenness is formed on the linear projections, and minute barbed projections are provided on the fishhook. 2 After providing continuous or intermittent streak-like protrusions in the axial direction on a wire or similar material used as a fishing hook material, and applying a rotary blade or cutting tool to the streak-like protrusions to form irregularities on the streak-like protrusions. A manufacturing method in which a fishhook is formed by passing the fishhook material through a hole having a diameter slightly smaller than the diameter including the convex portion, and then providing a minute barbed projection on the fishhook. 3. A manufacturing method for providing minute barbed protrusions on a fishing hook by reversing the process of providing streaky protrusions and the process of providing unevenness in Claims 1 and 2 of Utility Model Registration. 4. A manufacturing method in which a blade is applied diagonally to a wire or similar material to form a fishhook to form diagonal irregularities, and then minute barbed protrusions are provided on the fishhook to form the fishhook. 5. After forcing the wire or similar material used as the material for the fishhook through a rotating press that has concave portions along the circumference where protrusions are to be formed, to form continuous protrusions,
A manufacturing method in which a fishhook is formed after the fishhook material is passed through a hole having a diameter slightly smaller than the diameter including the projections, and minute barbed projections are provided on the fishhook. 6. Rotating a wire or similar object that serves as a fishhook material having a circular or almost circular cross-sectional shape with a gentle convexity, and moving it in a uniaxial direction, and applying a rotating blade or a fixed blade diagonally to the fishhook material. A manufacturing method in which a fishing hook is formed by pressing the material or the material through a rotary press that has irregularities along the circumference to form diagonal irregularities, forming irregularities in the material, and then forming a fishhook. 7. A fishhook provided with minute barbed projections formed according to statements 1 to 6 of claims 1 to 6 for utility model registration. 8. After providing an array of minute barb protrusions on the wire or similar material used as the fishing hook material in Claims 1 to 5 of Utility Model Registration, twisting the material so that the arrangement of the array of minute barb protrusions becomes spiral. A fishhook with minute barb protrusions that form a fishhook after being used.
