Few of us have ever heard the term Gummi Stone,
although the pros use them every day to polish, de-burr
and de-tune edges (see
tuning tips). There are several types of materials,
grits and sizes available. EdgeTune has chosen a medium grit, durable
compound aluminum oxide in a convenient size that fits
both your hand and your pocket.
This compound is also the choice of pros.
Note: this stone also works great to polish knives and scissors.
