Vintage Fuji Teuchi 78mm Blade Japanese Straight Razor
It looks it has never been used, and it has still paper case in vintage mint condition (the box describes Finest Silver Steel, so it might be different model box).
Overall, I am not sure what kind of the steel is used.
It might be around 1960s to 1980s Japanese straight razor made.
Teuchi means Hand Forged in Japanese (engraved the Chinese characters on the shank on the blade. It is on the side by the Fuji letters).
The blade length: 78mm (3 1/8 inch)
The total length of the razor when it opened: 252mm (9 7/8 inch)
The shoulder width of the blade: 6mm (3/16nch)
The width of the blade: 20mm (3/4nch)
The total weight of the razor: 2oz.
