I have benn using cromium oxide on a large pad of newsprint scetch paper from Strathmore insted of a strop and for me this has worked out great, I just use the Crox like a crayon on the pad then place it on a table with the paste side on the edge and so far great results. its lft and the sheets underneth gives abit of cusion, after the paste I stop abit on the un-pasted paper it being like news paper without ink, before I goto my excellent KenRup El Toro. anyone else use this?
