I've heard the Arius is heavy for it's size. I'm not really a Ti fan, buy @Monofletch has/had a Holt and said it was really nice, and the pictures I've seen reflect that.8 voted Haptic.
However, at close to $1k, I prefer customs. Really, anything over $500. My R&H Knives Tasca 2 was a custom order, green fat carbon scales with Odin's eye damasteel was $930.
I have an Alan Davis that is gorgeous, though is a very light duty knife in how thin the blade is.
I also really like Cheburkov and Biryukov.
There are a plethora and a half of options, don't limit yourself to just those four.
