I have some of it.

It's slow on the grinder, but if you keep the sharpening at the tip (which is generally how a lazy person like me goes about it), diamonds cut it pretty well.

It's nice to have a chisel or three like that one around in case you're flushing wood to metal on an infill plane. You can use a carbon steel chisel, but I only have iyorois and they don't like that. Western chisels for that are out of the question.
