I don't usually jump into the middle of threads, but finding the right neck knife took me a while so I thought I might have something worthwhile to say here. Finding the right necker seems to be almost as personal (and subjective) as finding a watch that really works for you. That said, I was at both ends of the search pole in terms of how long it took for me to find one. The Perrin (made by Fred) LaGriffe was immediately, for me and my training, the perfect martial arts/self defense knife. But it is not an EDC.
I went through A LOT of EDC neck knives (a real pain as those of you who do that know) until I finally hit on Tom Krein's midtech Dogfish and bingo! Worked for me as soon as I got it and then it was only a matter of getting the chain to the right length. What's funny is I'll probably use the bottle opener as much as the knife...but that knife will go with me on all my treks and fishing trips even though I carry a fixed and a folder those times. Without really being snobby about the whole thing...a midtech or custom necker isn't that expensive and the quality of one of those versus production (not counting BRK&T) is, again in my opinion, worth the price and the wait to find one.
