My advise:
- get a 4-5" blade
- stretch your budget a little to $250 or so
- browse the knife maker section on the Exchange, see if a custom knife catches your eye. In many cases, these are better than run-of-the-mill production knives
- make sure you get a good sheath, and that you like the way it's supposed to be carried. _Very_ important for long-term use, IMHO.
- pick a tough steel with a little chrome at least. M4, A2, 3V, AEB-L, Nitro-V, Elmax, CPM 154, etc. Will be much easier to maintain in the long run.
Have fun shopping !
