My entry into Case slipjoints was via a trio of Seahorse Whittlers, followed up by a trapper. They had the misfortune of following slipjoints from Solingen, Germany made by Boker (Tree Brand Classics) and Puma, as well as US-made Bucks, here. The worst example of those knives which I own came sharper and more easily deployed than the best of the Case knives I have. Of course, those Seahorse Whittlers do have two springs for the main blade to work against, so they are a bit stiff. I feel that Case knives are great 'collectibles'... but not so great pocket knives. The greatest aggravation? New, at least one Whittler and the trapper have secondary knife drag marks on the main blade. Even my ancient Buck 301 and Boker trapper still don't have that - after decades of use. The Bokers are generally cheaper, too - if you shop.
If the OP wants a great value in a US-made knife - get a Buck 301 Stockman. From in the $30-$40 range (MSRP $52) with black Delrin scales to several hundreds smackers in stag, choose your poison. Mine, in Delrin, was bought in Gatlinburg, TN after I found myself knife-less while in The Smokies. It's carved a lot of things, from flutes to walking sticks... and toothpicks!
