Instructions for the use of the Cutting Edge TechnologyWhite Honing Channel™ Sharpening Stone

These are the basic instructions for the use of our line of sharpening stones. More complete details are available at the time of purchase, and we will even send you a FREE video with your order.

  1. Lubricate the channels with sterile gauze soaked in water or cold sterilizing solution to help keep the metal filings of the curette to be sharpened from clogging the channel. Flat surfaces of stones can be used wet or dry.
  2. Hold the stone firmly on a hard surface such as a countertop.
  3. For those instruments that do not fit easily in the narrow channel, simply use the wider channel.
  4. Seat the working end of the instrument at the far end of the channel with the toe pointing awayIllustration D from you. The side of the curette blade to be sharpened must rest parallel and engage either wall of the channel (Illustration D).
  5. Rotate the instrument so that the entire length of the cutting edge is in firm, steady contact while hugging the channel wall tipping the entire cutting edge of the curette against the channel wall at least to the angle of activation or greater (Illustrations C & D).

    This would be similar to when one activates the cutting edge against the root of a tooth. Some degree of tipping is necessary. Sickle scalers can also be sharpened using the wider channel.

  6. Draw the instrument and its entire cutting edge in the direction of the instrument's heel maintaining firm, steady contact while hugging the channel wall. (Fig. 2)
  7. The conical side of the sharpening stone is designed to reshape and smooth the facial surface of the instrument from heel to toe. The face of all curettes should be smoothed, initially, when they come from the manufacturer, and occasionally, when there is a need, during the life of the instrument to correct any flaws incurred in usage (Fig. 3).
  8. Check the instrument for sharpness using the enclosed acrylic sticks. Hold the acrylic stick vertically and then place the curette's cutting edge against the acrylic stick at the angle of activation (approximately 80°), similarly to when one activates the cutting edge against the root of a tooth for root planing. When properly reshaped and resharpened, the cutting edge will bite into the acrylic with minimal pressure (Fig. 4).

  9. CLEANING -- Because of the impervious nature of the stones, the fine metal filings produced by the sharpening process stay on the surface of the stones and do not interfere with the sharpening or honing process. These can be easily removed by scrubbing with sterile gauze or cloth soaked in water or a cold sterilizing solution. Any water soluble household cleaner such as a scouring powder and a nylon dish pad, nylon brush, or wash cloth can also be used.
    For detailed instructions, please refer to the written directions OR video included with your purchased product(s).
To clean the channels - use firm pressure to sandwich a thin piece of wet cloth or gauze between the channel needing cleaning and a dental curette. Draw the curette with the wet cloth or gauze through the stone channel. Repeat as needed during the sharpening process. The sharpening stones are fully autoclavable while the clear plastic test sticks are cold sterilizable. The raspberry red plastic test sticks are fully autoclavable.
If additional cleaning is neccesary the stones can be soaked overnight in Muriatic Acid (Hydrochloric Acid) 20 Baume (31.45%), following all the precautions and directions found on the bottling label of the Muriatic Acid. In addition, these above services are provided free of charge if the sharpening stones are sent to us with a payment of $7.95 to cover the return shipping and handling.

In summary, the Honing Channel™ is designed so only the cutting edge will be in contact with the stone at any time during the sharpening stroke. The White Honing Channel™ Sharpening Stone's uniquely engineered design minimizes instrument abrasion (conserving metal), and maintains instrument shape. Sharpening is uniform across the entire length of the cutting edge of the curette restoring the extremely smooth, rounded design of the lateral surface of the working end. The stone's fine grit smoothes and polishes the instrument's working edges, thereby eliminating any serrations on the facial and lateral surfaces of the cutting edge and leaving no wire edges Improperly worn and damaged instruments can be reshaped and resharpened using the White Honing Channel™ Sharpening Stone, but this will take a little longer. However, the new Chocolate Honing Channel™ Sharpening System was designed to accelerate the sharpening process and is especially effective in quickly sharpening improperly worn or damaged instruments. A very sharp cutting edge having length but no thickness will be achieved following the above directions with the creation of two extremely smooth surfaces coming together.
