Japanese vintage razor Shotiku 33

Such Japanese razors were usually made of high carbon steel (炭素鋼 tanso-kō), using traditional methods with carbon-rich white steel (Shirogami) or "blue steel" (Aogami).
In terms of workmanship and period, Shotiku 33 is probably made of high quality Japanese carbon steelfor achieving a very sharp edge. Stainless steel was almost non-existent in these older models.

The seal consists of:

• 正貴 (Shotiku - master's name/sign)
• 作 (saku means "made")
• 33 (model or batch number)

This is a traditional Japanese straight razor made of high-carbon steel, with the Shotiku mark and model number 33. This razor can be very sharp and long-lasting when properly sharpened, but requires maintenance (as carbon steel tends to rust).
