It starts out innocent enough, trying out new grinds, new locks, new handle materail.... Soon you figure out what you like, and by then you are addicted to that new knife feeling.
That one where you say "this, yes THIS IS "The One,"" soon enough that feeling goes away after two or three weeks, and your back on the exchange looking to buy/trade. I'v traded/sold knives I loved, just to try out new knives... then like a true junkie only end up emailing the person to ask if they ever sell to please give me first shot.
I'm not saying I'm out of control or it's ruining my life, I just know I was happier when I only had a Vic midnight manager, Mini Manix, delica 4, and a full SE pacific salt

Carried the Manix in right front pocket and SE salt in left front pocket for well over a year.
My job would not permit this type of carry now, but I'm still thinking simpler may be better. Going to tuck them away for awhile before I do something il only regret later.
It's nice to know I'm not alone.
