Gamakatsu hooks are considered by many to be the world's finest. Their extreme chemically sharpened points and special tempered high carbon steel wire strength are second to none, and jig hooks are forged for an additional level of strength. Gamakatsu has their own unique sizing, and the heavier wire 604 version we use generally appear to be a little smaller than other brands with the same size #. The new 2x Gamis used in the salmon-steelhead ball heads are even heavier wire and stronger than strong! Gamakatsu hooks command a premium price but you get what you pay for.
