Decorative Lines on Munesaki?

[EmmaNZ]

Hi,

 

Is there a name for the decorative (I assume) lines that are sometimes visible on a sword's Munesaki, as shown in the photo?

 

 

Thanks!

They are also often found under the Habaki, between the Munemachi and the Yasurime

Here's an old thread with some good photos of Nagashi

Best of luck,
Cheers,
