Sharpening the Universal Curette L For Left Handers
Sharpening the Universal Curette R For Right Handers
Instrument Position: Hold the instrument vertically in your non-dominant hand. The blade to be sharpened will be at the bottom with the toe pointed toward you. Brace the side of the top shank with your thumb and place your elbow directly in front of you on the table. Position the terminal shank at 12 o’clock. Stone Position: Place the lubricated side of the stone against the right lateral surface of the blade. In an upright vertical position, initially direct the top of the stone upward toward 12 o’clock and then tilt the top of the stone away from the instrument to 3 minutes after 12 o’clock. Stone Movement: Initiate grinding in a fluid up-and-down motion. Start at the heel third of the blade then continue to the middle third and finally the toe third. Remember to maintain a continuous up-and-down motion using long strokes with moderate pressure. You should see a buildup of sludge along the entire facial surface of the blade. If you are using a ceramic stone you will see a buildup of metal filings instead of sludge. Using gauze, wipe the sludge or metal filings from the surface of the blade and stone. Sharpening the Opposite Cutting Edge: Rotate the instrument so that the toe is pointed away from you. Maintain the secure palm grasp and again brace the top shank with your thumb. Repeat the grinding process keeping the terminal shank at 12 o’clock and the stone position at 3 minutes past 12 o’clock. Rounding the Toe: To maintain the rounded shape of the curette toe, rotate the instrument so that the toe of the blade is directed toward 3 o’clock. Position the stone horizontally under the blade and tilt toward the 2 o’clock position. Move the stone in a consistent up- and-down motion, overlapping the strokes and rotating around the toe to maintain the rounded shape.

Rounding the Toe: To maintain the rounded shape of the curette toe, rotate the instrument so that the toe of the blade is pointing at 9 o’clock. Position the stone horizontally under the blade directed at 9 o’clock and tilt upward toward the 10 o’clock position. Move the stone in a consistent up-and-down motion, overlapping the strokes and rotating around the toe to maintain the rounded shape.
