Allows the knife being sharpened to be secured in the gap formed between the two jaws of the holder clamp by the two clamping screws using hex. wrench #4 and the holder clamp nuts.

Adjusts the angle of the edge at the end of the knife depending on where the clamp is installed. If the clamp is installed closer to the end of the knife, the edge angle at the end of the knife will increase. If the clamp is set closer to the handle of the knife, the edge angle at the end of the knife will decrease. Proper clamping of the knife ensures the same bevel and edge angle along the entire blade.

Allows the fixture with a knife to be mounted on the ADEMS Tesar machine with the spherical part of the sleeve resting on the axis of the knife stop by fixing it with the wing screw and the knife touching the abrasive band by adjusting the sharpening angle.

The position of the sleeve relative to the axis of the device and the knife holder relative to the swivel stand determines the knife sharpening angle.

Using the sharpening holder, it is possible to adjust three radii of the shape of the edge angle of the knife being sharpened:
- Large radius;
- Normal radius;
- Small radius.

The holder allows you to sharpen a straight section of the cutting edge of the knife being sharpened by moving the fixture along the axis of the stop until the beginning of the cutting edge rounding. Then, when sharpening the rounded cutting edge, a rotary movement is added to the longitudinal movement. After sharpening the cutting edge on one side, the knife is resharpened on the opposite side by reversing the fixture with the knife, similarly repeating the procedure for sharpening the cutting edge on the opposite side.

If necessary, you can study to work on the machine both face-to-face at the International Academy of Sharpening ADEMS, and remotely via the Internet or video courses.
