All my other katana came with pre-tied knots which looked so complex I left them alone, however, this new one made me do some research into how they are tied. I found an excellent video from Hyoujinsama on YouTube (one of his many excellent videos I may add) and attempted to tie a sageo knot myself.
My first few attempts were poor, to say the least, but after some practice, I managed (what I think is) quite a good knot. The biggest problem I had was that the sageo was too short for a third loop, but too long for two loops. I ended up wrapping the loose end around and tucking it into the back, pulling everything nice and tight. I'm sure some traditionalists will have something to say about that! How should I have done it?
Anyway, below you can see two pictures of my Hattori Hanzo "Bride" katana from Kill Bill. I don't normally go for movie swords, but I did like this one quite a bit. Despite being a movie replica, it features a 1065 hand forged blade (razor sharp) with a genuine Same (Rayskin) tsuka, iron tsuba and brass fittings. Not sure who makes it, but I think it may be a Musashi. Good quality blade, although the hamon is etched. The fittings are great and fit nicely and for me it has a really good balance and the leather wrapped tsuka feels perfect for my hands.
