The honing compound contains a combination of micro abrasives and polishing components (average grain size 3 micron).
One application lasts for about 5–10 tools. Work the honing compound into the leather. The leather honing wheel will become saturated and more efficient the more you use it.
When you have a new honing wheel, impregnate it first with a light machine oil so that it gets the right texture and can absorb the honing compound.
If you work in a dry climate, you might need to re-impregnate the honing wheel after some time with a few drops of oil before you apply fresh honing compound. Do not let the compound dry, apply more oil if necessary.
