Skilled and frequent use of these high quality waterstones will guarantee that a tool or knife edge will always be at its best. Synthetic waterstones are manufactured by sintering metal oxides with a binding agent. Their soft, friable bond allow fresh abrasive to be continually exposed to the surface being sharpened, resulting in a for and fast and precise cutting effect. Due to their softness, these stones must be treated with care and trued regularly. Please take not of the following recommendations:

USE
Before use, soak the stones in water for at least 15 minutes. You can also store the stones in a closed, water-filled container. This method, in addition to saving time, keeps the surface of the stone clean and free of the salt and lime particles which otherwise tend to accumulate in the pores. Disinfectant may be added to the water in small quantities to avoid an unwanted build-up of bacteria and algae. Do not use dishwashing liquid or caustic household cleaners. To use, remove the stone from the water and place it on a level, non-slip base (e.g. rubber pad or sharpening stone holder). Always use the entire surface of the stone to prevent uneven wear. In order to make full sue of your stone's sharpening potential, the fine abrasives which accumulate during the sharpening process must be regularly rinsed off. Otherwise, a paste will form on the surface of the stone which will reduce the abrasiveness, causing it to act more like a finer stone. This effect is often desired and te paste itself ca be specifically produced using a Nagura stone.

RECONDITIONING AND TRUING THE STONE
Uneven stones can be trued using one of the following methods:
  • Place a sheet of strong glass on a flat table and lay a wetted piece of wet abrasive paper on it. The paper will automatically adhere to the glass by suction. For coarse or extremely worn stones, use 80-100 grit paper. For stones with slight irregularities only, use 150-180 grit paper. Rub the stone against the paper using a circular motion while continually adding water, until the stone's surface is completely flat.
  • The most effective option is to use a special truing block

GENERAL CARE
Sharpening stones which have become clogged with debris can be reconditioned with a man-made Nagura stone or by truing (see above). Japanese water stones must be handled with extreme care due to their porous, friable structure. Avoid breaking or damaging the surface by handling them with care and covering then when not in use. A thin or worn out stone may be protected from breakage by mounting it on a piece of hardwood using epoxy glue. This will greatly increase its lifespan.

NOTE
Combination sharpening stones are held together with waterproof glue and the seam at which two stones are joined is often visible. This does not impede the function or durability of the stone.
