Types of wooden handles：Japanese White Oak（Shirakashi）

Accessories：Original wooden box

Additional Information: Unused, the six chisels are in brand new condition, But the box has some stains.  I found this from a professional tool shop in Chiba.

There are two marks of chisels made by Funahiro on the market: one is "Funahiro/舟弘" and the other is "Genju Funahiro/元寿舟弘". The steel used in the chisels of these two marks is different. 

"Funahiro/舟弘" mark chisel uses White steel No. 1.

"Genju Funahiro/元寿舟弘"  mark chisel uses White Steel #1(C 1.38% vacuum arc redissolved) . Some stores also say it is "Original New Japanese Steel". Compared to this vague description of steel, I prefer to believe Mr. Ishikoso's research report(現代鍛冶技法の保存調査報告 その2［舟弘］銘・船津祐司の鑿製作) published in the Takenaka Carpentry Tools Museum Research Bulletin No. 25 in 2014. Page 13 of the report records the steel used for the Funahiro chisels and planes.
