I finally found something, a post (link here), by Richard_L on 02-05-11. It looks as though Rader = Evergood = Zhen. He says:
I actually bought a 300mm/12" Evergood VG-10 gyuto a few months ago, but at the time I was so busy, I didn't have time to play around with it much. Initial impressions: decent F&F but definitely not on par with, say, Shun. Handle shape looks nice but not great for pinch grip because of the pronounced palm swell. Spine was very sharp, so I had to round and polish it. Decent edge out of the box, but probably could use some thinning. I think I'll dig it out of the box this weekend and put a finished edge on it and try it out some, maybe.
Unfortunately, he didn't follow up, but the impression he gives is that it wasn't that bad a knife, for the price.
