Manufacturer's name or trademark: Some traditional Japanese axe manufacturers will engrave their own names or trademarks on the axe to show their identity and quality assurance.
Symbolic words or patterns: In addition to the name of the producer, the axe may also be engraved with symbolic words or patterns such as Kendo, Kanakubo and Unknown. These names and patterns have certain symbolic significance in Japanese culture. For example, kendo represents the samurai spirit and the traditional skills of mountain cities, while Kanakubo may be a place name or a person's name, while ignorance means that this axe has no clear sign or mark.
