For the guard, we have selected a hairy guard that is not too strong and has carefully selected materials. While exhibiting snagless performance, it can flexibly fall in any direction during a bite and does not interfere with hook setting. We have realized the reduction of slipping, which can be said to be the fate of guarded trout hooks. In addition, due to the characteristics of this guard material, it is easy to modify the shape of the guard after catching a fish.
