I own a couple Case knives, and am happy with their current production line. Other than my Bose Tribal Spear, I have a Sodbuster, Bose backpocket and humpback stockman from their current line. The sodbuster and BP are great knives. Only complaint about the humpback is that the spey blade is a nail breaker and too thin to get a good purchase on when opening it. They are often railed on, and I am guilty of it too, for their SS steel. Their CV is great, their fit and finish isn't bad, the edges on their SS blades could be better, but they are easy to sharpen for the average user. Many of their offerings are made for the collector market.
When you look at the other major slipjoint manufacturers, Queen and GEC have their need for improvement. Queen is famous for not always sending blades out with a good edge, and GEC's are known as being nail breakers, until they are "broken in". Bucks are good knives, and their 420HC, while not a super steel, is better than SS from Case.
While it will cost you, if you can, get a few knives from each company. A Case swayback jack, which seems to be very popular on this subforum, in addition to a Buck 301 or 303, would be a great start. Just to get a feel for what works for you.
BTW, I found a well used and little loved Case double jack knife, with red bone scales. It has a half stop, carbon steel blades, and still has walk and talk. Little bit of wiggle, but not bad. From the 50's. You can still find useable old Case knives in thrift and junk shops.
