「岡恒の剪定鋏」の研ぎ方を徹底解説。（フル字幕付）クロダシャチョー

This video explains how to sharpen Okatsune pruning shears so well that you will no longer need to watch anything else but this video.
It is perfectly explained in accordance with the official opinion of the manufacturer, Okatsune.
In addition, we have added our own explanations on how to sharpen the angle of the blade and how to sharpen the receiving edge of the blade.

Sharpening from the back of the blade is very little. If you sharpen it too much, the sharpness will deteriorate. In that case, you can correct it by sharpening the blade from the front until the edge is sharp.

I use a diamond sharpener, which is easy and quick, and I do it myself as it is. I recommend this method because it is both more time-effective and economical than using a whetstone.

There are other videos on tool maintenance, so please watch them as well when you have time. I will continue to release more and more videos that you will enjoy and find useful.
