Thread: Raven Barber Hone Info?

I asked these question already, but am wondering if I might have posted them in the incorrect area (under Honing instead of Hones), so here's part 2....

I am looking into purchasing a Raven barber hone online. It is in very nice condition, (price removed! sorry for confusion) in almost new condition. I currently have a Norton 8000/4000 water stone that has been wonderful to me, and gets a very nice edge on my razors. However, I have been looking into picking up a barber's hone because of the legacy behind them as well as getting an even finer polished edge. I have been looking at all of the previous posts in the SRP forums about Raven barber hones, and have still have a few lingering questions:
Are raven hones durable? I understand that they are quite hard, but do they tend to chip?
What is the grit (approx would be better than an estimate) of a Raven? I don't want it to be too high, as too fin of an edge would just chip, but I would like it to be higher than 8k, because then I'd feel like I wasted my money on it when my Norton has an 8k side.
Should I keep a Raven (or most barber hones in general) submerged in water between usages? I keep my Norton 8k/4k submerged in water, but that's designed for it.
Any help would be great!
Here's a link to one of the stones that I'm looking at. It seems to have a few chips on it near the top, but they're on the side, so it shouldn't affect honing....but I figured I'd leave it up to the experts to tell me more! There are pictures you can see from different angles if you click on the image of the hone. There are 5 pictures total, I believe, and the hone is shown wet and then how it looks with the water dryed on it.
