I think most of use who have accumulated a good pile of knives don't use many of them or use a couple all the time. Look on the bright side. If those were firearms at $500 or more a pop, you would really think that hobby expensive. I have seen folks just getting into guns who go on a buying spree and pour a lot of money into it very quickly.Honestly, I haven't used quite a few of them. I use the Dua and HK 14715 everyday at work. Nothing has pushed them out of my pockets. I use the Siegle quite a bit in the yard. The rest either get carried on the weekend or not at all. Some will get their chance to be users, some will move on. It's a great hobby, but also expensive.
6 months into knives...lots of knives, but zero cash left.
