Nagano 3" Double-Sided Diamond Stone

The Nagano 3" double-sided diamond sharpening stone is a practical choice for speed skaters who want to maintain sharp, consistent blade edges. With two different grit grades on a single plate, it allows you to carry out multiple sharpening stages without changing between separate stones.

Its 3-inch (76.2 mm) width provides a generous working surface for controlled sharpening. The diamond abrasive is distributed evenly across the surfaces to promote consistent contact and predictable material removal. This makes the stone suitable for regular maintenance of both short track and long track speed skating blades.

Choose a coarser side when more material needs to be removed, then switch to the finer side for a smoother finish. The available grit combinations let you select a plate that matches your preferred sharpening routine, whether you want to combine coarse and fine sharpening or work with two relatively fine surfaces.

Another advantage is the straightforward maintenance. The diamond surfaces are designed for dry sharpening, so no water or sharpening oil is required. After sharpening, remove loose residue with a dry cloth. The double-sided construction also makes the stone convenient to carry to competitions, training sessions and skating camps.
