IF the volume is there.

Several places on line advertise $16 per inch for custom knives. Not bad until
you consider a jointer has three blades.

But yes, it is all about volume. The pulverizor mill at my work has disks that
are over five grand a set and IIRC around $700 to have sharpened. However, they
will grind over three million pounds of plastic before needing to be
re-sharpened so the cost per pound is insignificant.
