Hook size: #4/0

Using extra heavy wire, the gap part is designed to be flat. A special treble hook for catching big fish in salt water.
What I want to emphasize is the hook point, which has a two-stage taper with a precision sharpened point. This shape is the result of a shape that is strong enough to counter the phenomenon that only the point part bends inward when hooking into the hard part of the mouth with GT etc.
