I have mixed feelings about Case. I like my fairly recent CV yellow barehead trapper, despite the small flaws in it. I've seen a few that were kind of disappointing considering the price. And the last two Case knives I bought, both small economical lockbacks, went back because the blades would fold with the same pressure it takes on a slipjoint. Really disappointing. Most Case knives, though, seem aimed at the collector market.
Sad to say, but American made production slipjoints are a variable lot, and often not a good value, IMO. Honestly, it's difficult to beat a simple, inexpensive Victorinox when it comes to slipjoints.
