摘要： An object of the present invention is to provide a readily manufacturing a fishhook having the barb whose angles and shapes can be freely changed correspondingly to purposes of use. A method of manufacturing a fishhook according to the present invention is characterized by: applying machining process for providing a sharpened part at a tip of wire to constitute a fishhook; and applying pressing process for making into a plate-like shape a part in continuation to the sharpened tip part; and further applying simultaneously or sequentially in free order machining process for forming a stepped part at one lateral side of the plate-like part and machining process for cutting out a swollen portion produced at the other lateral side of the plate-like part, whereby forming a point part or a fishhook.

摘要： A flared double fish hook having a pair of shanks, said pair of shanks adjacent one another up to a bifurcation point; the shanks bifurcating at said bifurcation point to each form a bend ending in a point; the shanks being separated by an first angle at the bifurcation point, and a second larger angle at the points, such that the bend portion of the double fish hook flares.

摘要： A method for forming a barb of a fishhook including the steps of pressing a thin flat portion of the tip and either cutting or chipping a part of the barb to form a rear face on a side opposite the tip of the hook. At least either upper or lower lateral sides of the hook tip may be cut to form flat or concave lateral cut faces with a sharp edge along a ridge at a juncture of the lateral cut faces.
