Not being critical here...but I don't get the appeal of knife collecting (and I have a good friend that's got a substantial collection...)

It's a tool--it seems to me it'd be like saying "I've got a great hammer collection" (and yet I'm sure there are folks that do collect hammers...)

Do we all have some kind of a "collection" gene--and we have to collect somthing?

Baseball cards, knives, Yi-Gi-Oh, Beanie Babies, cameras, fishing poles, string, NFTs--the list goes on forever...

What is it that compells us to accumulate "stuff" of a certain type...

Thoughts?
