  • STONES: Oil/Water

    I have an old combination stone that has been used dry for sharpening kitchen knives for at least 40 years. How do I clean the old metal off the stone, and how do I tell if it should be used with water or oil? What makes a stone an \\\\\\\"oil\\\\\\\" stone or a \\\\\\\"Water\\\\\\\" stone? TIA!

    The purpose of either the oil or the water is to flush away the swarf = the slurry of metal particles and smashed abrasive particles. That keeps the stone cutting at its labelled grit size.

    My best rehab is to use lots of oil/water and scrub one stone against the other. Almost as good is to soak the stone for a while then a dang good scrubbing with a clean brass-bristle BBQ grill brush.

    If your stone has never been used with either water or oil then the choice is yours. Veg oils may oxidize and go sticky/gooey over a long time. There\'s water in the sink. Handy and non-toxic.

    I\'ve got one that I found in a kitchen drawer at the lake. The bone handle suggests to me that it\'s really old, never seen another one like it. Very fine grained, gray color, cylinder thick as a finger and dry. Use it for my kitchen knives and cleavers. Lots of gray dust. Sharpen cleaver, wipe dust off on jeans. Put rod away, prepare food.

      What RV said sounds good.
