Difference between flow hook and sleeve hook

I know that the flow hook and the sleeve hook are obviously different in shape and use. The creek hook is wide and suitable for fishing in running water such as streams. Because it is often in contact with stones and gravel, it needs certain strength and wear resistance. Sleeve hook is thin, mainly used for fishing small fish such as crucian carp and carp. It is simple in shape, easy to manufacture and replace, and can better penetrate the fish mouth and reduce the damage to the fish. Choosing the right hook is helpful to improve the success rate of fishing and the survival rate of fish.
