Technically it follows the format and style of a classic makers mark used on Chinese swords and the characters translate to be: 古浸懂理
This reads as Gǔ jìn dǒng lǐ which means something like "Ancient immersion theory" so is not actually a name or makers mark but is something that is a made up expression.
I asked around and no-one knows of a maker in China who uses this, so it looks like it is just a stylized add on.
If anyone else knows anything different, please feel free to add your $0.02 accordingly.
