This is a traditional large sword sized wooden sword that can be used in a wide range of ways, from Kendo style to Iai Kenjutsu. Currently, the lack of wood (oak) is noticeable and the original cutting period (dry season) is not enough, and the material in the rainy season is also unnecessarily available. As for the strength, our craftsmen have contracted that they are identical to traditional white oak, so we appreciate your understanding.
