I make sure not to feed my kids stuff they don't like so they don't start liking them; I made that mistake once with cold pizza.My son says he doesn't like some foods he's never had. I tell him at least try it before you decide you don't like it. Sometimes you may be pleasantly surprised.
For me, and only for me as I can't speak for others, I like knives and in this hobby it's more of a "why not" for me.
I can purchase a knife and if I don't like it put it on the exchange and be out a very small amount of $ (hopefully).
I see nothing wrong with stepping out of my comfort zone to see something, use something, feel something for myself.
It helps me form an opinion that is based on experience rather than an opinion based on pictures and assumptions alone.
I'm glad I did, actually.
Then I can continue to enjoy them myself without having to share.
