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
I 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.
I don’t think there’s a blade that doesn’t get duller with time, is there?
Ceramic is less prone to get dull, but it still not a 100% solution, and once you go dull you never go back. Sometimes it even chips.
I had some years ago. They ended up chipped as hell. That's when I bought some halfway decent (not good, just not Target grade) steel ones that aren't stainless. I hone the ones I use most a couple of times a week and the rest of them on an as needed basis. I sharpen them as needed.
If your schedule and executive fiction allow for it then I highly recommend it. Ceramic is sharp as fuck, but not enough sharper to deal with buying a new one every time it chips.
Ceramic knives are kinda stupid yeah. But a ceramic "steel" to hone your metal knives works amazingly. And those don't chip, because they're round. They can shatter though.
Yeah, I bet a ceramic honing rod is pretty great. I've seen them as a part of some of the better knife sharpening sets.
So could you smash car windows with these bits? Are they like the snake bite things made out of smashed up spark plugs?
Just curious if it’s the same type/grade of ceramic, or if this stuff would just continue to shatter/bounce off.
And no, I’m not planning on smashing up at knives at Target in order to rob the cars in the parking lot.
Go do that at Home Depot after you smash up a few display toilets.
Okay, I stand corrected.
Technically 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.
So sharp it cut itself
They said it was sharp, not uh, the opposite of brittle
the 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.
*They're
I’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.
a single atom thick?!
Gotta love ceramics...

Yeah, I think I'll pass on an engine that might just as soon crack if dinged with a pebble from the road.
