Hey they're not lying, it definitely looks sharp
I bought a set of "metal drill bits" really cheap. First time I tried to drill metal they just melted
But I couldn't argue with the fact that they were indeed, metal drill bits. Just not drill bits for metal
86I know someone who bought a cheap drill bit, and on first use, the twist got straightened out
It's as if they didn't harden it

Yeah, ceramic knives are like that. They get duller with time however.
37I don’t think there’s a blade that doesn’t get duller with time, is there?
33Technically diamond? But cutting bits are only large as like 2mm, and are very expensive. Diamond also can't support a very steep cutting edge, so you will be limited by possible edge geometry. Used for machining highly reflective, perfect, mirror finishes on parts.
TLDR you're right

It's true. It's sharp. However, that doesn't mean it isn't brittle.
29So sharp it cut itself
22They said it was sharp, not uh, the opposite of brittle
6the opposite of brittle
I think that would be "tough", which has a mathematical definition in materials science: https://en.wikipedia.org/wiki/Toughness?wprov=sfla1

You actually can sharpen ceramic blades but its a pain and their super brittle. But for cutting light tasks their far far superior. I've used many of them.

4I’ve never been able to sharpen them. But I can sharpen my metal knives.
I highly recommend carbon steel Japanese knives. They are absurdly sharp and hold their edge for a long while. They can shatter like this sometimes, though a lot less dramatically, and usually after being dropped. They also need to be treated similar to cast iron, since they can rust if not cared for. Get one with a stainless cladding so you can just sharpen your knife if you accidentally let the blade rust.
Granted, I do a ton of volunteer work that involves a lot of food prep, so I need a knife that is sharp, holds an edge, and chan be sharpened as needed. I hate buying knives that will eventually need to be tossed because I can’t sharpen them. I love my Nakiri and Kiritsuke so much, can’t recommend japanese knives enough.
