The stone is the right size to take with you on a hike. Suitable for sharpening a knife, like an ax.
Somehow stays on the table if you want to sharpen while holding the knife with both hands. On the stone side, for example, the Mac was sharpened again by grinding 2 times per side. The imprint on the steel was so good that there was not even a need for a diamond.
The flatness of the stone is just enough for quick sharpening, much better than in the old one.
Takes care of its job despite its small size.
