The Spyderco Wegners are hard to beat. If you check around, some of the Internet knife sale sites could probably fix you up. I really like mine, especially the smaller one.
The PUMA lockbacks are good knives as well. I found the blade steel to perform better then the comparable Buck you get from Wal-Mart or some other mass marketer. The cut out for the 'clip' seems a little excessive to me. It makes for great piercing but, there just isn't enough blade left up front for mundane things like spreading cream cheese or peanut butter.
A Buck 110 with a BG-42 blade, whether a Master Series or one of the BG-42 incarnations, is another great choice. It certainly will appear more sporting to the 'sheeple' then just about any other knife. The Buck 110 is a legendary blade along the lines of the classic Swiss Army Knife.
