Thanks B-man for pointing out the angle of the Barcalo broaching as I never gave much thought to the scooped box ends. Here is a shot of a Barcalo made but Crescent branded 15/16" combo. I have a small Barcalo 6pt combo done the same way. I think it gives the box end a cleaner look with the angled broaching.
I took an instant like to that design as soon as I found one years ago - been slowly putting together mixed brand sets of combos and dbl boxes.
