The purpose of this note is to acknowledge the help from Forum members in identifying and obtaining a mineral oil for the leather honing wheel. I was uncertain about the oil used to soften the surface of the leather honing wheel. Identifying it as a mineral oil clarified everything. The terms white oil and pharmaceutical oil appear to be used in special marketplaces for ordinary mineral oil. I was able to obtain a small quantity of mineral oil from a distributor. So the honing problem of microscopic scratches is now solved. The wood chisels are razor-sharp without tiny curls at the edge. And they cut wood fiber precisely. The T8 with the Japanese Waterstone is working as promised. Thank you!
