~ Polishing craftsmen are amazing! ~
When a knife becomes dull, it is sharpened using a whetstone, but if it is sharpened by an amateur, it may end up being dull. The angle at which the knife and whetstone come into contact is important, but amateurs cannot maintain this angle, so the edge of the knife is rounded during polishing and cannot be sharpened.
Polishers can maintain the optimum angle between the blade edge and the whetstone, so they can produce sharper knives than amateurs.

What is the relationship between kitchen knives and screen printing?
A squeegee is very similar to this in screen printing.
In the past, the author was researching how screen printing could reduce printing variations. I knew that the condition of the edge of the squeegee would affect printing variations, so I experimented while adjusting the polishing conditions.
However, I was at a standstill when I was one step closer to my goal.Some people said that it would be good to wet the squeegee with solvent and polish it, so I tried it, but it didn't work very well. Even if you think that the whetstone of the polishing machine is bad and replace it, it is not enough. At that time, I heard a rumor that there was a famous squeegee sharpener in the village.

would you like to try it once?
With a squeegee in hand, I knocked on the grinder's door. "Master, please sharpen one squeegee." I asked, and he took out fine sandpaper and started sharpening the edge of the squeegee wrapped around the juice can. It looked like he was sharpening a Japanese sword. After a while, I said, "all done," and handed the squeegee to the author. I was surprised when I touched the edge of the squeegee with my hand. It looks like the tip of a knife. There is no rough feeling before polishing.
Print with this squeegee and be even more amazed.The film thickness is perfectly uniform! I tried to imitate a squeegee grinder, but the author's inexperienced polishing did not reach this level.
The tip of the squeegee is important for print quality.
