Woody,
it's funny that David used the word Quaich as that was my first thought when I peeked in this morning. Especially as I had turned one only a month ago for a toast for the Piper at a Regimental Dinner. Then I realised that there were 4 corners, not 2 handles so it was a one of your bowls.
I like the way you've managed to keep the lines flowing either side of the square rim, and keeping all 4 corners sharp and attached is an art in itself.
