Every Diamagroove starts as a raw steel rod in Ralph Whitman’s hands and leaves the shop as a precision‑engineered grooming tool built to last.
From solid bar stock to machined cores, and ready to finish product, each piece is designed, cut, and built in‑house for maximum balance, cooling, and control on the nail.
The Diamagroove’s industrial diamond surface is engineered to stay cooler, resist clogging, and maintain its shape far longer than traditional sanding bands.
