Topic tags/keywords: question

I was recently given three diamond hones. There are no markings as to grit. one is yellow, one is blue, and one is red. Any idea what the grits are, or if this is a color code?

According to the package my set came in:
Yellow – Coarse
Blue – Medium
Red – Fine
I wrote the grade on the back of each one with a Sharpie.

Yellow is Independent – can badly sharpen steel

Red is Democrat – can only sharpen on end of steel

Blue is Republican – Can only sharpen the other end of steel
