GRS now has a version that is round with a leather top that was suggested by Sam Alfano. Like Ray's, which I have enjoyed, the GRS version sits flush with the inside edge of one jaw. As a result, it works when drawing on something held between the jaws, such as shown above, but it covers all the holes on the top side of its jaw, so you can't use pins in that side to hold something.
