Carl,
In the late 1970's, while I was in the Navy and endlessly at sea aboard one combatant or another, I did a lot of scrimshaw work. To me, it was exactly the type of thing a sailor should be doing in his minimal spare time and with no work shop or tools other than a knife and a sail maker's needle. For a soldier, far from hearth and home, making a powder horn and decorating it with the designs of his campaigns and sayings that touch his heart is the epitome of the art...and in its proper setting. Bravo Zulu.
I wish you "fair winds and a following sea".
God Speed, Carl.
