Here is pair of Stanaback Specials in Box Elder, I believe.

I believe the butt caps are "thinned & rounded". Thinned referring to the height of the butt cap from the top, down. Rounded refers to the absence of a sharp edge on the circumference of the butt cap. I believe "rounded" and "radiused" are the same.

This should hold us until the Captain returns. Beautiful wood on both.
