I have a No. 7 in carbon, polished the the blade, didn't like the grind ridges, but I'm not sure if they are normal as most of the pics I've seen seem to be smooth. I was sharpened a bit, but during the polishing I took the edge to a proper paring knife grind (scandi I guess) It is my kitchen knife, as I like having a sharp knife for food prep where ever I am (it lives in my EDC backpack) and I can't leave a knife in the kitchen as my room mates tend to kill them. It has a very nice patina, I've noticed that different fruits impart different colors, besides the base gray there are also some purples and blues. I've also rounded the butt of the handle and taken the sharp corners off of the ring. My buddy calls it a bottle cork with a blade, but I think he is planning to add one to his camping kit. Best slicer I own by far, (not that I own many) but it works nearly as well as my high end chief's knife (lee valley peasant knife) just not as good at prying frozen stuff apart. I'm probably going to add an 8 or bigger to my camping food kit, just because they are so nice to use. and as far as peeling fruit, how about cutting sandwiches without ripping them apart, or cutting other delicate foods, the looks I get from a blade that sharp and cultured looking are sweet.
might have to get a 12 for cutting watermelons.... and another 7 for my girlfriend..... good thing they are cheap! maybe cut one apart and carve a handle out of UHMW polystyrene, that would be interesting, not grippy, but cool looking, or a block of home made polyester resin and fiberglass, or auto store carbon fiber... this could get fun!
