The Huel Friendship Mino is gibberish (most likely a corruption of the transcription,) however there is a Wheal Jewell & Friendship mine in the Tavistock area. I'm going to get one of these bloody stones if it kills me.

If you get one may as well get two while you're at it IOW, I would love to have a stone that,"has considerable local repute for sharpening all kinds of thin-edged broad instruments" and would pay for the privilege.
