>>2862359Most knives that aren't made of cheap chink pig iron and scam steel will last your entire life and do everything you need a knife for, even one of those cheap $5 stock plastic folding knives can easily last you decades with bare minimum maintenance and tons of abuse.
Because of this, anything you buy like this is specifically for personal use preference and fashion. I've used a slightly shitty folding buck for 18 years and it has never once failed me, and if I ever need to replace it it's like $20.
That said I have a good collection of knives that I got entirely because they look cool, and I almost never use 80% of them and probably never will.
