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

It's true. It's sharp. However, that doesn't mean it isn't brittle.

So sharp it cut itself

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.

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.

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.

Yes, but these can't be resharpened

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
