What term refers to a small diamond with a sharp edge used in kerfing or polishing tasks?

• A. Girdle
• B. Culet
• C. Table
• D. Sharp

Answer: (D)

In polishing and kerfing, the effectiveness of the abrasive comes from the edge on the tiny diamond used. A small diamond with a sharp edge concentrates cutting action and removes material cleanly, which is exactly what you want for delicate kerfing cuts and fine polishing grooves. The other terms describe parts of the diamond itself as a gem (girdle, culet, table) and are not about the abrasive tool used for kerfing or polishing. So the term that best fits is the one that denotes this sharp-edged diamond used as the cutting/finishing tool.
