Hey Kalsu, I'v been using a Case damascus peanut since March of 2011, and it's been a very good knife. It has the Thomas raindrop pattern damascus and it's the only damascus blade knife I have ever had, so my experiance is limited to this knife. It's weird stuff. It seems to take a toothier edge than CV or stainless. Even when it gets a bit dull over time, and it looses it's finger print grabbing edge, it still cuts very well with a slice or draw cut. It may not push cut worth a darn after it looses it's razor edge, but it laid across a piece if hairy jute twine, it has no trouble slicing right though it. It never seems to loose that toothiness that will cut if dragged across something. LIke I said, it's weird stuff, and does not behave like any other blade steel I have used.
It does seem to be harder to sharpen than my CV peanut on the same 600 grit diamond hone. I can sharpen up my CV Case in a few minutes, but the Thomas damascus takes a bit longer, and seems more stubborn to get a final edge on. On the other hand, like said, it will cut longer after loosing the initial edge.
It's weird but neat stuff.
Carl.
