What's the difference between ZDP189 and VG10 as far as steel qualities go?
VERY good question. I have a gray Caly Jr and the VG 10 is very impressive. The caly Jr is my favorite under 40-50.00 simply because of the amazing VG10. It's supposedly around 59-60Rc which is a fairly hard steel, but very easy to sharpen in my experience. The flat ground blade in the Caly is great, especially for slicing chores. And I like the finger choils which give you more control than the Delica IMHO.
Now, my NEW ZDP 189 CalyJr just arrived today and I just took it out of the box. It has a laminated steel with a center of ZDP and sides of 420J2. The ZDP should be around RC63 which is very hard and the 420 is extremely stainless. In theory, it should hold an edge much longer the the VG10, and still be tough due to the 420. I don't know how hard it is to sharpen... the factory edge is adequate for now, and if I polish it up later, I'll report back.
I have compared VG10 to S30V and I really don't notice much difference. The VG10 takes a somewhat 'toothier' edge, which I prefer. I'm hoping the ZDP will be on par or exceed these in edge quality and holding...
The ZDP caly just was released a few days ago, so hopefully we can start to give some real feedback soon. I and many others have one of each, so we shall see.
EDIT: If I had a another choice, I'd pick the Victorinox Soldier (or farmer). Softer blade steel (which isn't really a big deal, since it is thin, flat ground, and extremely easy to sharpen), but the real beauty is that you can pry, hack, drill, mark, drive hardware, open cans... anything that you shouldn't be using a knife blade for. More compact and classier looking than the very utilitarian Spyderco's.
