There is at least one mine in Slovakia (Rozsutec) producing natural whetstones for both scythes as well as bench stones. My scythe stone cost 2€ (~$3). While its true that natural whetstones are non-renewable, I would suppose that there is not any real danger of running out of stone to make them from anytime in the next several thousand years. Only, there doesn't exist much economic incentive to find new quarries of suitable stones. Were there in the future increased demand for natural stones, then there would be an incentive to find/open new quarries.
