I know it is very hard to narrow it down to just one or two of your favorite knife manufactures but try! If necessary give a top 3. It can be a custom knife maker or a factory maker, any and all are welcome!
I started out with an addiction to Kershaw knives and still get the newest ones to come out but ever since Ken Onion said that he will not be designing knives for them anymore I was kinda bummed. Right now my favorite knife company would be Benchmade and then Spyderco coming in very close second. I switch between the two when buying a new knife so that I have a balanced collection from each company.
