My friend: That's a phenomenal idea!!!
I carry this
Almost always with me, as you can see is a fallkniven DC4 and a double sided handmade leather strop one side with polishing compound) but with the ceramic rod I could refine the edge to a higher level, I don't know when I'll have some time but I'll try a pocketable prototype for sure,
Thank you very much for the invention.
P.S. where did you get the ceramic rod??
