I have no experience with RW's knives so I can't offer a comparison. However, I do have a couple of Ivan's -- a slim fighter & a tanto (pix on the fixed blade page of my "Toys" site) -- with a third on the way. The slim fighter has a nice horizontal polish while the tanto's blade is etched, more of a field finish. The handle wraps on both are impeccable & the sheaths are very nicely done as well. (The slim fighter's is lined with velvet which makes for a particularly smooth & silent draw.)
Also, a friend has one of Ivan's Kiridashis made from 6 mm thick K-100 steel. Although the blade is short, this is not a flimsy little utility piece. The thick steel gives it a nice amount of heft and the full size handle makes for a very secure grip.
It looks like RW makes some nice knives but I know that Ivan does. I'm sure you wouldn't be disappointed.
