Come along with me as I dive into the world of knife sharpening in Japan, to visit a knife specialist, Hirose-san, at his locally-famous shop "Sanshodo," in Otsu city, Shiga prefecture.

If you find yourself in the area, stop by and see Hirose-san's selection of high quality domestically hand made knives at very reasonable prices.

Echizen Uchihamono's Knife Making Process:
The 19 Steps shown in the video:
1) 地金 (Jigane) - Unprocessed metal
2) 鋼 (Hagane) - Steel
3) 地金割 (Jiganewari) - Splitting the unprocessed metal.
4) 割込み (Warikomi) - The Wedging Process, where the steel part (2) is inserted into the casing of unprocessed softer metal (1)
5) 沸し付け (Wakashitzuke) - Forge Welding, where the metals are heated to a high temperature and hammered together.
6) 半型取り (Hangatatori) - Forging a half shape.
7) 中子取り (Nakagotori) - Forging the core, or tang, of the blade.
8) 二枚広げ (Nimaihiroge) - Widening two sheets, where two sheets formed in the previous steps are hammered and fused together.
9) 焼なまし (Yakinamashi) - Annealing, where the metal is heated to around 800 degrees C, and the stress points of the knife are made uniform. After that, the blade is cooled.
10) ベト落とし (Betootoshi) - Removing the pits and divets.
11) 荒ならし (Aranarashi) - Rough leveling
12) 裁ち廻し (Tachimawashi) - Trimming, where the knife is cut into its desired shape and unnecessary bits are removed.
13) 本ならし (Honnarashi) - Main leveling
14) 摺り廻し (Surimawashi) - Sanding, where a belt sander is used to create a smooth surface of the entire knife.
15) 焼入れ (Yakiire) - Tampering, where the knife is hardened by heating to a high temperature.
16) 荒研ぎ (Aratogi) - Rough sharpening, where a grindstone is used to create the first form of the blade edge.
17) 縦研ぎ (Tatetogi) - Vertical Sharpening
18) バフ研磨 (Bafukenma) - Buffing
19) 仕上げ (Shiage) - Finishing
And there you have it!
