Back in the 1970s I owned a custom leather shop in Savannah with a few friends. Belts were one of our big sellers and I stripped out, beveled, tooled, dyed, oiled and finished thousands of belts along with other stuff. I also custom made all leather, hand cobbled sandals. All of the sandal straps were beveled too. Beveling the sharp edges on hard leather really makes a difference in their comfort and and softens the appearance.
