This. Thank you Benjamin for taking my scything to a new level. Until now, I had been sticking to the dicta Vido, following which a serious mower only considers the finest stones, coarse stones being rubbish.
Turns out, these are perfectly legit. They may cause more wear to the blade - but definitely less to the mower !
