こんな研ぎ方はどうですか！？刃物研磨機の簡単な水循環システムをご紹介！研ぎ環境を改善しよう【ボイスマン GK21S2 電動刃物研ぎ 回転砥石】

Knife sharpening can be hot in the summer, cold in the winter, and uncomfortable in terms of posture. But I wanted to be able to work comfortably in an air-conditioned room, in a position of my choosing, so I came up with an inexpensive water circulation system. While there's still room for improvement, being able to use it while standing or sitting in an air-conditioned room has made sharpening much easier. I'll keep looking for better solutions, so I'd appreciate your input! #knifesharpener #knifesharpening #HIKOKIGK21S2 #rotarygrindstone #coarsegrindstone #knifesharpening
