Just for clarification, the word sissi is a Finnish word that comes from the root sisu, and refers to a person who has great endurance and stamina, or is indomitable.So, just quit calling it a scandi grind. It’s a saber grind.It still has the Sissi thing to contend with, though.
As to the blade grind, there is nothing new or mysterious there. Its no different than anything else the military might be using.
