What is this leaving of which you speak? I don't believe I am familiar with the term.
Infatuation, Justification, Appropriation, Obsession, and Resale
Infatuation: You see it (internet, show, store, dealer, friends) and you want it. You may or may not have told your wife at this point.
Justification: You convince yourself why you deserve this knife. You may or may not have told your wife at this point.
Appropriation: This involves obtaining the funds to buy the knife. Could mean the resale of other knives. You may or may not have told your wife at this point.
Obsession: This is a 2 part gig. Waiting for the maker to complete your knife as well as deliver it. It is far easier if the knife has already been made or factory and only needs to be shipped. The second part is after it arrives. This includes fondling, stropping, oiling, modding, carrying/using, taking pictures, posting on forums with pictures, and finally the obligatory youtube video. Also may include buying a duplicate to put in the safe. You may or may not have told your wife at this point.
Resale: May lead to another knife starting this cycle over. You may or may not have told your wife at this point.
