Sharpening the Sickle Scaler R For Right Handers
Sharpening the Sickle Scaler L For Left Handers
Instrument Position: Hold the instrument vertically in your nondominant hand. The blade to be sharpened will be at the bottom with the tip pointed toward you. Brace the top shank with your thumb and place your elbow directly in front of you on the table. Position the terminal shank of the blade being sharpened at 12 o’clock. Stone Position: Place the lubricated side of the stone against the left 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 before 12 o’clock. Stone Movement: Initiate grinding in a fluid up-and-down motion. Start at the heel third of the blade and continue to the middle third and finally to the tip third. You should see a buildup of sludge along the facial surface of the blade and stone. 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 the stone. Sharpening the Opposite Cutting Edge: Rotate the instrument so that the tip is pointed away from you. Maintain the secure palm grasp and again brace the top shank with your thumb. Position the terminal shank of the bottom blade upright at 12 o’clock. Tilt the top of the stone slightly away from the handle to 3 minutes before 12 o’clock. Repeat the grinding process maintaining the clock position. Using gauze, wipe the sludge or metal filings from the surfaces of the blade and stone.

Curved Sickle Blade With the tip of the blade pointed toward you, hold the terminal shank at 12 o’clock. Place the cylindrical stone on the face of the instrument with the stone placed horizontally, at 3 and 9 o’clock. Lightly rotate the cylindrical stone along the face from the heel to the tip to remove any wire edges.
Straight Sickle Blade With the tip of the blade
Straight Sickle Blade With the tip of the blade pointed toward you hold the terminal shank at 12 o’clock. Place a flat stone horizontally on the facial surface of the instrument at the 3 and 9 o’clock position. Move the stone from side to side with light pressure to remove any wire edges.
