The TUFF appears to be a great knife and I don't worry too much about rust. Since I'll be carrying it (if I end up with it) everyday it'll be consistently cleaned and wiped down. How does the edge hold up on the TUFF? I've never had a knife in 3v. If I read correctly, it's not as wear resistant as s30v, but how short is it? I rather enjoy sharpening, but the 8cr and 14c28n I've been using lately really don't seem to hold up well.
Also the spyderco military is growing on me. For a very long time I was very very against it from a style standpoint, but it has grown on me. I'm not 100% sold on the shape, but it has transitioned from a patent refusal to consider to a tentative preference for some other styles though it does have an excellent price.
