I'm the same way.  I buy a lot of knives but I sell a lot of them also and I try to keep current inventory to a minimum of what I use regularly or have an important emergency use for (such as my kit knife).  I try to keep my overall inventory of not just knives but all kinds of "stuff" to a minimum.  I kinda like to feel like Im going through life travelling light. <img src="/images/graemlins/smile.gif" alt="" />  But I still maintain that there's nothing wrong with having toys. <img src="/images/graemlins/smile.gif" alt="" />
