I'me getting hooked on this knife thing. I've ordered a fillet knife from Bill Bryant which hasn't arrived yet and I'm shopping like crazy. Here is the target zone: a folder, serious edge holding, substantial corrosion resistance, blade about 3", maybe a bit more, a reliable locking mechanism, partly serrated, (but haven't totally decided on that issue), and there are financial limits on this deal - I'd like to not clear the century mark by too much. To do so requires artful dodging, which can ratchet up to prevarication, or worse yet, whining when caught. Can blades of BG-42, CPM440V or 420V be had in that price range? If not, what's next? And, what knives might be recommended?
