It's been mentioned already, but the Vic Soldier I got back in 2002 is still going strong. It's not as pretty as my other EDCs, but it's probably the best value out of all of them. Sharpens up great, has perfect fit and finish, and is an ideal size for me. I do have to admit though, it's got a bit of a sterile feel to it compared to some of my bone handled stockmans and trappers.
Another low cost quality knife is the Buck stockman that my girlfriend got me this Christmas. Yeah, it's made in China, but it's a fine knife that's grown on me. If I think I'll be abusing a knife that day (and for me that could be something as small as knowing I'll have to cut up a few boxes - I'm not that hard on my knives), this is the one I generally put in my pocket that morning. It's a great size, sharpens up nicely, holds a pretty good edge, has great fit and finish, and just feels like a quality product.
Oh, another worth mentioning is my Case CV amber bone medium stockman. What a nice knife. Probably gets more pocket time than any other knife I own. But I won't gush over it here, public displays of affection are just annoying. I love the stockman pattern and own stockmens that cost serveral times more than this knife, but this is the best of them all.
And another (I just can't stop thinking of them...) would be me Case yellow handle single blade trapper (I think they might call it a utility knife). Love this one as well.
I have more, but I'll stop...
Thanks,
