Why do we recommend sandpaper?


1. You can whet it in a short time.
2. You can exchange the sandpaper of various grades @ easily.
3. It is expensive to collect various whetstones.

Why do we recommend re-whet of one surface of the knifeH
Rockstead knives have a finished surface like a mirror.

One side is whet by the fine sandpaper. The other side keeps its original surface.
Both sides of the edge have a finished mirror-like surface, this method is called the simple whet method.

If the polishing grains are lost, you can change the sandpaper very easily.


The polishing grains are already attached to the sandpaper.
So you can perform effective polishing immediately.


The edged tool is polished with the grain which came out from the whetstone.
The size of the grain is not constant.

The polishing grains are in the whetstone.
If polishing is begun, the grains will come out of the whetstone.
