I've only got 7 knives and one sword, other then one fixed blade and one folder I edc most of the rarely see use, and the ones that do I've made excuses as to why it needs to be used (9" blades on pizza, because pizza cutter is a pos etc lol). Only four of those knives can even be edced due to laws. Money is tight right now so I can't keep buying, but if it wasn't, I'd probably end up owning more.
You see, I have this problem, where I randomly browse knifecenter or Amazon and look at several different knives, and think about how each blade shape or length would be more useful for this scenario (dumb things like justifying tuff lite solely for box use, which is stupid considering 90% of my edc is opening crap), then comes all the crazy shtf scenarios or the survival scenarios regardless of the fact I haven't had the chance to even be much outdoors for a few years.
If money was no issue I don't think I'd be content until I had one of everything, despite the fact I'll rarely use half of it.
Don't know what it is about knives but there's some sort of primal urge to collect and have as many knives as possible lol.
