I have a small amount of safe queens (50 or so) that will never be used but these are high end (to me over 150.00) knives, now I don't intend to keep them with the intention of hoping they increase in value but rather I keep them because I like to pull them out every now and again to admire,play and just fondle them for lack of a better word and want to keep them pristine. Now all of my other knives I EDC on a regular basis and have and do use them all
