Universal Stone Holder for Work Sharp Professional Precision Adjust is equipped with a digital angle gauge holder and a stone-changing pin.
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.

For any steel type, I would recommend going to something like a Venev diamond resin based F800 and F1200 (Fepa-F grit rating) stones. If, for some reason, you want to mirror polish your edge after this then use a diamond pasted on a strop.
If you're only ever sharpening legacy type steels (not modern super steels) then you can stick to ceramic based aluminum oxide stones.
