I think of us all as "Knife Knuts," or some similar spelling, and use that in these forums, but I use the term "Knife collector" when refering to myself while talking to Non Knife People. I don't consider myself an actual collector, as my knives all get carried and used, but those nerdy connotations of stamp/comic book/baseball card collector, etc. go a long way in bringing our obsession into a realm of normalcy, and out of the percieved world of crazy.
