I've bought some customs that were too nice to use and so they just sat there...I tend to buy on a whim sometimes without thinking it through.
this is the reasoning i have for a couple of purchases; the most glaring one (and still have) is a Buck 110 Bloody Jasper. i cannot use that knife; it is "too pretty" and i will never buy a knife that is too pretty to use ever again.
clearly i am not a collector LOL...it has no utility for me and just sits...and i hate that...
