【賛否両論】笠原将弘さんの愛刀・柳刃包丁『旬 ダイヤモンド砥石』で切先まで丁寧に研ぎ上げる

We're maintaining a cherished yanagiba knife (a fully forged yanagiba knife) entrusted to us by Masahiro Kasahara of "Sanpi Ryōron" (a Japanese comedy duo). Kai Corporation's knife master, Yasuhiko Hayashi, will use his expert skills to sharpen the hard, uniquely "fully forged" blade to its absolute limit. This time, we'll demonstrate a full-fledged sharpening process using a diamond whetstone. The way the knife then effortlessly cuts through paper is truly a must-see. This video showcases the luxurious pursuit of sharpness, packed with professional techniques. Please take a look. ▼Table of Contents (Chapters) 00:00 Opening - Introduction of Mr. Kasahara's beloved knife (traditional forged) 00:54 Checking the condition of the knife and planning the sharpening process 01:46 Correcting the blade edge with a diamond whetstone (#1000) 05:13 Reducing thickness and adjusting the blade line 09:24 Finishing sharpening (#4000, #8000) 14:15 Final check and back sharpening 14:38 [Demonstration] Sharpness check (paper test cutting) 15:02 Ending - Presenting to Mr. Kasahara ■Kai Corporation Official Online Store https://www.kai-group.com/store/?utm_...
