Thank you for your question--it was quite interesting to look into. I wasn't certain if you were asking what this object was used for or how it was made. 

It was used to sharpen safety razors (for shaving).  I am attaching a copy of the patent from England for this patent number. It provides a detailed description of the item, including how the surface of the glass was created.

Let me know if you have additional questions.
