01 / ABOUT
Meet Kenshi Ryota
A chef’s perspective.
An artisan’s hands.
The joy of sharing.
Craftsman at JIKKO
Knife sharpener, blade finisher and video creator
Hello, I’m Kenshi Ryota.
From Japanese cuisine to the craft of sharpening.
My approach to sharpness draws on my experience using knives in a professional kitchen. A blade’s structure, its condition and its relationship with the whetstone all guide my daily practice.
I also want to share what makes sharpening so fascinating. On social media, I create videos that make sharpness visible. On YouTube, I explore sharpening techniques and the knowledge behind them.
Began working as a Japanese cuisine chef
at a members-only resort hotel in Arima Onsen.
Became a knife sharpener at JIKKO.
Pursuing the craft of sharpening and blade finishing.
