I had and used the Bugei Samurai katana; it is very strong, but a tad heavy for most folks. I ended up selling it.
I've owned the Bugei Wave katana for about ten years now. I've cut with it many times, and have only had to sharpen it by lightly touching it up a couple of times. I would recommend Bugei swords to anyone willing to spend that much cash on a sword. The Swedish Powdered Steel they use is very durable, and the swords are put together very well. The Wave katana from Bugei is fast, strong, and sharp...despite many poor cuts in the past, my blade has never taken a bend. When I first got it years ago, I tested it on a few 2" oak dowels...the blade was flawless afterword...no chipping at all, and still sharp. Out of the two Bugei swords I've owned, the handles were both way too tight. They shimmed the hell out my wave's handle, but I was able to give it a more proper fit. I choose the leather handle wrap, and it's still as tight as the day I got it. I can't imagine you would be disappointed at all with your purchase. The only thing that sucked was it took 7 months to get it. Good luck, let us know what you decide.
