My original post was confusing. Allow me to clarify.
Forum: For Sale: Custom Knives (Individual) here on BF has a plentiful daily flow of flippers/folders for sale, most of them are NIB or LNIB. The quality designation tells me that many are buying/holding/selling flippers and folders or trading out of their collections, not their EDCs.
So, if collectors are selling/trading their flippers and folders out of their rotating collections, why aren't owners of custom/handmade fixed blade collections doing the same?
Sorry for the confusion!
