>>1045350That is the stupidest shit I've read all day anon.
more durable material and easier to sharpen with better edge retention
you can only cut so well no matter the knife
we'll probably never have steel as sharp as obsidian, but that doesn't mean every knife should be obsidian. You use different materials for different purposes, and a knife more than a few inches would be impossible to make out of obsidian, even ignoring the economics of even making it, much less maintaining it, but it would be extremely brittle.
You don't judge a knife solely on how well it cuts. You judge it on ergonomics and shape of blade, weight, durability, features (like a guard, a double edge, saw, etc.), hardness, and edge retention, just to start.
Your problem is either you're buying shitty knives, or you're expecting knives to be razor sharp as you buy them. The reason those 10$ knives are so sharp is because they're made of trash stainless steel, soft enough to easily sharpen, but they generally wont hold an edge for shit.
I bet your problem is you're a 20-something that was never taught how to use anything but a basic sharpening stone to care for his blades.
