At this point in my collecting career, I've got quite a few knives that cost me more than $500, and at current*, my favorite would have to be my Spartan Harsey SHFs, with my Shiro F3 in strong second. I won't lie, though. Most evenings, I'll have three or four knives on my side table and I'll just sit there and fidget with them, strop one or two, and call it good. It's one of my favorite forms of relaxation.
As for actual use, SHFs can handle that quite well, and so can pretty much all of the others I own. Olamics, my CRKs, my custom Doziers, several others.
* Which, let's face it, is the only objectively relevant metric with knife guys because you know it's going to be a different answer next month! LOL
