I have quite a "collection"-but they are all for different purposes. I may have three machetes and 8 axes, but for someone that uses them somewhat frequently, there is a world of difference between each.
For the average user, one axe is enough to get by for their whole life.
I often carry a fixed blade puukko style knife (such as a mora #1 or a WoodJewel Carver) on my belt next to my hammer loop, and noone seems to notice or particularly care. I did have a fellow once ask me if I was carrying a fillet knife with a hint of amusement in his voice, but that's about it. Everyone on construction sites has a blade of some sort, most often it's simply a folding knife handle that takes disposable blades, but it's a cutting tool just the same.
I'm young, and I enjoy going out dancing in clubs and hanging out with my friends around town in addition to my love of camping, bushcraft and running. In those cases, I often carry a smaller knife, like an Opinel #7 that I've had for a while. If I'm concerned about being searched for whatever reason (hasn't happened yet), I will carry a multitool or Victorinox.
I think at this point I'm beyond being a knife nut, even though I still highly value knives as tools, and nearly always carry one. I don't make as many excuses to use a knife anymore, I pretty much just use one if the need arises. I've stopped constantly talking about knives, unless it really makes sense to bring it up (or someone else brings it up). My encyclopedic knowledge of steel times and quenching temperatures is even slipping
And I've hardly been spending any time on bladeforums reading about knives...
