Sewing use, bone, spatula, Showa, retro

I was organizing my sewing box at home and found this bone awl from the Showa era.
The top is inscribed with Gokujo (Supreme Quality), and the bottom has a flower design.

Would this be of interest to sewing enthusiasts or those who love Showa retro items?

Thank you.
