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 don’t think there’s a blade that doesn’t get duller with time, is there?

        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

        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.
