Jaquette 1 Sickle Scaler
All sickle scalers have blades that have a trapezoid cross section, with two cutting edges, either side of the top face. Sharpening is performed on both lateral faces; the top face should not need to be touched.
|
1. Taking the instrument in the Pen Grip, place one of the lateral faces at about 30° to the stone.
2. Move the face forward and backward against the stone, putting pressure on it in a pull direction.
3. Turn the instrument over and perform the same action with the other lateral face.
4. Test the tip for sharpness (if there is evidence of a rough 'wire' edge, remove this using the stone rod in a rolling motion).
|
 |
Make the final stroke in the pull direction (into the cutting edge) to remove any wire edge.
H6 Sickle Scaler
This tip has the same, nearly triangular, blade cross-section as the Jacquette 1, but it has a much longer
cutting edge and the blade is offset. As before, sharpening is only performed on the lateral faces, the top edge should not need to be touched.
|
1. Taking the instrument in the Pen Grip, and place the blade flat to the stone.
2. Angle the handle to 45° to the stone.
3. Push the instrument forward and back over the stone, but apply pressure when pushing the instrument away.
4. Test the tip for sharpness and remove any wire edge.

McFarlane 1 Push Scaler
As push scalers are used in the opposite direction to all other scalers, they are also sharpened differently.
|
1. Taking the instrument in the Pen Grip, and place the blade flat to the stone.
2. Angle the handle to 45° to the stone.
3. Push the instrument forward and back over the stone, but apply pressure when pushing the instrument away.
4. Test the tip for sharpness and remove any wire edge.
|
 |
Take care when positioning the hand holding the stone so that you will not injure yourself should the scaler slip while you are pushing.
