Advanced Stone Holder for Work Sharp Professional Precision Adjust equipped with a linear ball-bearing offers a new level of precision and comfort. The advanced stone holder lets you achieve flawless results even with challenging tasks.

Universal Stone Holder allows using ANY rectangular sharpening stones:

• 6" Professional Precision Adjust diamonds and blanks
• 6" mounted stones (Edge Pro format-factor)
• 6" flat-end stones
• 4" mounted stones
• 4" flat-end stones

Note. It's very important to keep a sharpening angle consistent. The angle should not change when progressing to the next stone. If the thickness changes, the sharpening angle changes. Unchecked, this can ruin your sharpening. Use a digital angle gauge to monitor the sharpening angle when you replace a stone in the stone holder. Use the angle adjustment knob of the sharpener if necessary.
