Having (almost) completed my first mount of a KC 26, I am looking at my next project. A fried of mine (1st Dan Bujinkan) has aked me for advice and help with his first live sword. The obvious choice for him would be the Cheness Oniyuri but an alternative migh be a Ronin Ko Katana with a longer Tsuka. Of course this would only make sense if the nagako on the Ronin would be long enough. Does anybody know how long the nagako actually is on their Ko Kat ?
