All my knives have to be POTENTIAL users, otherwise I don't want them. Meaning NO WALL HANGERS that can only look pretty. I don't use all my knives, but they have to be user type if you know what I mean. There's not one single knife I wouldn't use if I needed to.
To this point, that's me as well.
I have a lot of EXPENSIVE Busse Combats that I don't want to use, because of loss of value...however...if I needed to I know they're the best of the best.
Having said that, I'm starting to consider selling off those in favor of a smaller core group of knives that will actually get used.
