I found information about nihontos getting heavily crisp if used to kill, not only by blade on blade contact but also on flesh/bone contact. however i couldn't find an explanation for the damage and an assumption on how much a nihonto can "cut" without the need of repair/replacement .
i assume this is also connected to the Wazamono tests 1797/1805
i would also like to know wot the difference between a Saijô-Ô-Wazamono to a Ô-Wazamono or Wazamono class katana is, in terms of "life span in use" and damage. (i would appreciate an answer considering blade on blade and only flesh/bone contacts, thanks)
