Please explain the term...skin cut...thanks.
“Skin cut” is a current term for very very shallow letters. A stone is polished to mirror gloss, a template is glued on and sand blast (sometimes steel shot) takes the polish off. Depth may only be one sixteenth or 3 thirtyseconds. After that there is u cut and after that there is v cut. V cut usually requires a no polish panel to be more visible as the letters darken as they v out.
