I personally don't own one but I've been researching this sword for sometime.
The Shinto is the best katana in it's price range, period. It's a major step up from the stainless wall hangers, but still lags far from the top end martial arts grade swords that'll cost $1500 and up.
If you got your heart set on a Shinto, make sure you are getting the new version. The new Shinto has a 11" tang, that's 5 inches more than the old. Trouble is they look the same on the outside and has no distinguishing item number from CASI (yet).
You should consider the other 2 swords, the Golden Oriole and the Musashi. I personally don't like the Musashi because it has that leather handle wrap.
I am thinking of getting the Golden Oriole and having the handle professionally shortened (present length is inaccurate), then have it re-wrapped with silk in the color of my choosing. The cotton wrap on these things is not martial arts grade and will fuzz with use.
I would not advise you to get one for martial arts cutting. The word is that QC is streaky. Sometimes the heat-treat is just right, sometimes the sword is brittle, making it unsafe for contact use.
Let me know if you wnat more.
