Judo points are used mostly in grassy areas for small game.
Fishing points are used for bow fishing and feature barbs to hold the fish to the arrow.
Broadhead points are used for big game and generally have interchangeable blades that can either be in a fixed position or a newer type, which opens only on impact.
Safety first! Always use a broadhead wrench when adding or removing a broadhead point. Careful! The points are very sharp!
