The recommended lubricant to use on bench whetstones like our Natural Arkansas Stones
is Garrett Wade's Premium Honing Oil. During sharpening, micro-bits of steel are removed from a blade which can clog the stone and reduce its effectiveness and longevity. To avoid this, use oil also to clean your stone after each use (ideally). Our Honing Oil is also a very good light-duty, all-purpose oil for your household needs. Available in 3 oz. & 16 oz. containers.
