My opinionated opinion:
Buy a damascus if you like the looks of one and have that kind of money to spend on a single razor. It will not be a Super-Razor that will hold an edge infinitely long. Your stainless Dovo probably will hold an edge as long as any other razor out there, as it is resistant to corrosion, which is a chief cause of edge degradation. My Dovo Renaissance holds an edge extremely well.
OK, so if you want to spend $790 for a razor, it will be an awesome razor, no doubt.
Personally, I'd suggest you try a LeGrelot 1/4 grind from rasurpur.de. It's not stainless, but carbon razors aren't that hard to maintain (I'm a fan of stainless for ease of use, but right now I have 4 carbon, and only 1 SS). It is ~$175 delivered, and it is an awesome example of a heavier grind razor. Defeinitely will give you a different shave experience.
Personally I do find that I prefer a heavier grind, it gives me a much pleasanter shave experience. Full hollows will get me BBS, but don't feel so nice getting me there...
Or, as mentioned, Joe Chandler makes 1/4 grind custom razors (check out Straight Razor Designs), they seem to run about $450 or so?
Or the TI Super Gnome is a carbon 1/2 hollow. I don't have one, can;t say what they're like, but they can be purchased on Classic for <$100.
And of course, there is the ubiquitous Wapi 1/2 hollow. It is not nearly as beefy as the LeGrelot, and alslo not nearly as nice by a long shot! But it is super affordable ($22 new and unhoned, or ~$40-55 honed and delivered)
In summary:
If I were you, I wouldn't blow all the cash on one high ticket razor alone (unless you really, really want to, in which case, go for it!:D), when you could spend that $800 on a bunch of new razors, hones, strops, etc. and enjoy a full array of fun!
