Katori Shinto Ryu

I started making Koryu Bokken, at the request of Holland guy who practice Katori Shinto Ryu, by his words, one of the oldest schools of Kenjutsu in Japan

first Sugino Sensei Dojo

this daisho was make from European oak, 

Daisho was treated with red oil, until it reached the reddish color of wood, similar to Japanese red oak

next is Otake Sensei Dojo 
also European oak but oiled with regular oil,  

that would retain the natural color
