This is a very ordinary steel hammer. It is a small carpentry tool. Famous hammer makers include "Kozaburo Hasegawa," his disciple "Doshinsai Masayuki," and "Hiroki Aida." These hammers are not cheap, as they require high-level forging and welding techniques, such as using steel for the striking face to prevent damage and mild steel for the body to absorb impact. They are not tools for the average carpenter. I am also a collector of the precious wood "Yakusugi" (Yakushima cedar), and by using this material for the handle, I have enhanced the impact and feel of the strike, making it an easy-to-use hammer. Yakusugi grows extremely slowly, with about 20 annual rings per centimeter, resulting in extremely tight grain and a flexible material. The feel of the strike is superb. Total length: 300 mm Head: Weight: 217 grams, 58 monme Section: Length: 80 mm Section: 22 x 10 mm Square chamfered type Handle: Core material: 1000-year-old Yakusugi Hardwood reinforced on both sides for the grip Two of the same items are listed.
