Honing oil prevents metal shavings from clogging the pores of the stones. Metal shavings can build up over time causing the blade of the knife to be run across metal particles during sharpening. Oil helps suspend the shavings, allowing them float off the stone. Arkansas stones need oil during use to prevent clogging. Oil can also work as a cleaner and conditioner of bonded abrasive stones, such as Silicon Carbide and Aluminum Oxide stones.
