If it is a good Damascus and etched properly, it can be a great steel. Depending on the steels involved in the pattern welding if that is the kind of Damascus you are talking about. It can be easy to sharpen, develops micro-serrations over time which makes the edge holding a bit better, can have decent toughness, good edge holding. The downside is you may have to re-etch the blade if/when the pattern begins to fade. Not a huge project at all, but still something you would not have to do with a mono steel. I own a few and use them as edc's, but for real heavy use I will use a mono steel.
All in all, if you want a great EDC folding knife, I would go with a mono steel like M390/20CV/204P. It is a great all around folding knife steel!! Others are S35vn, CPM 154, Aeb L, Elmax, CPM 3V, PD1/Cru-wear, etc.
I do love the way Damascus cuts and sharpens, but if I had to choose one knife to carry it would have a M390(or its equivalent steels like 20CV or 204P) steel blade.
Oh, did not read the part about the "Sebbie". Can not speak about it in regards to CRK. I was talking about other knives.
