I think:
http://www.weatherlycustomdesigns.com/robb01.htm would be the best place to get one. He is not grinding during the summer but there are still some of his pieces from spring that either are not claimed or that were but were never paid and will be available soon. They tell me he is working 4 12s at his regular job right now so pretty busy.
I think his grind is just fine for general purpose. I have chopped branches including oak, boxes, milk jugs. I protect my wakizashi more than my bowies and such so have never chopped into anything I expected to hurt the edge. There is no damage from the oak etc. It is a little dull but that is the result of using it for the last several years without sharpening.
Every one I have seen gives high marks for the balance of his swords, I am going to go against the flow a little here. My wakizashi is incredible, VERY fast and well ballanced, it feels much more powerfull than the 20" blade would have you expect. The 31" katana I had did not seem well ballenced. Bear in mind that I am not familiar with katanas but it seemed like there was too much curve and it carried the weight too far back so that it wanted to fall over sideways. For all I know all katanas are that way but I didn't like it.
I don't think it would have the same problem with a shorter 28" blade and suspect he has fixed it in more recent swords. I like his improved style on the tsuba, he is doing most of them out of titamium now and they look really good.
If you like them but don't like the style of the handle wrapping or the kydex sheath get one and make your own handle or sheath.
I know what you mean about the Howard Clark blade, sometimes when I feel like wishing I go to:
http://www.summerchild.com/summer.html
and look around for a while. He has Clark blades from time to time.
I guess to sum it up I don't know what "user blade" entails to you but for me his pieces have been very usefull and I wouldn't part with my wakizashi from him for anything, well almost anything, now if someone offered me a Howard Clark with a Summerchild pollish......
