Here're six beasts encased into a A5 size cardboard chart, the Mustad 7734 Giant Tuna hooks ranging from size 6/0 to 11/0.
Forged along the shank till the tip of the point, it was therefore marketed as thrice times extra stronger than their regular steel i suppose. Knife edge point allowing easy penetration, which may also be sharpened using a stone.
Built largely for commercial fishermen targeting various Tuna Species, some anglers may use these for other big game fish. This model of 7734 has no longer been in production for a long while, neither found in Mustad's latest catalogs too.
J-shaped fish hooks such as this, have high occurrences of gut hooking marine creatures by being swallowed. As the results, un-targeted species like sea turtles are often critically wounded or killed due to J-hooks piercing into their throat/guts.
Tuna populations are over-fished while some species under critical level before extinction. Limits & bans are imposed on some areas, meanwhile conservationists work to learn of their breeding patterns for sustainability.
