I like the higher-end Case slip joints (non locking pocket knives) like the mother-of-pearl stockmens. Apparently, they have a collectible factor and can increase in price if kept in mint shape.
From a user perspective, I just don't like the unidentifiable steels that Case uses which I suspect is 420J stainless. But they are beautiful knives and I'd be thrilled to get one although I would be too scared to use it and abuse it.
If you are looking for locking blades, there are plenty of gentlemen's folders from most of the popular brands (Benchmade, Sog, Spyderco,...). Gentlemen folders are usually smaller (3 inch blade or less) than tacticals and have a more generic shape, and other cosmetic features like stainless steel handles.
An example would be a small CRKT Howard Viele Wasp (just off the top of my head), or the SOG Gentlemens (large or mini).
Remember Swiss Army Knives, and multitools make cool gifts too. Happy Holidays!
