Kestas

The reason I was asking is I know for a fact that it does extend the life of hardened steel cutting blades. In a place I once worked at, standard blades needed to be honed every 4 hours, and changed every two to three days.

The same exact blades, cryogenically treated, needed honing maybe once per day and lasted at least 8 full production days.

But if it only works on hardened metals, I guess there is really no app in an engine.

Thanks for the knowledge!
