I generally always keep a neck knife around my neck whenever I'm hunting or fishing. I use it a lot when fishing to trim line when tying on lures, cleaning fish, etc., and at least a few times a day for odds and ends when I'm hunting, whether I bag anything or not.
I bought the one shown in the top picture above, and plan to use it this summer, as I like it better than the one I've been using. I also was a little put off at first by the fact that it hangs down, but the fit is secure and I don't think it's going to be falling out of there. OTOH, it's easy enough to draw out of the scabbard when you need it.
I have plenty of beautiful knives that I will probably never use, but this is a practical knife that I plan to use every day when backpacking, fishing, or hunting.
