Welcome and enjoy! It's a great asylum, friendly inmates, look out for Nurse Wratched.
It may help manage the obsession to keep reminding yourself that it's OK not to be able to own (and store, and insure, etc) all 10,000 wonderful knives out there. OK to really appreciate and admire something and not have to own it. Or even want to own it.
Kinda like admiring but not coveting a best friend's truly wonderful wife.
