DOUBLE SIDE FLATTENING STONE: This innovative flattening stone features a two-sided, dual-grit diamond grid design engineered to create precise flat surfaces on sharpening stones. Constructed with high-quality silicon carbide, the abrasive particles deliver efficient material removal for accurate flattening. Designed for durability and performance, it cuts quickly and resists wear. UNIQUE DESIGN: The diamond-shaped grid pattern effectively removes only waste material, ensuring efficient flattening of various sharpening stones, including whetstones, oil stones, and ceramic stones. EXTRA LARGE SIZE: This double-sided flattening stone offers a significantly larger flattening surface, providing more coverage than standard stones and enabling full contact with larger whetstones. DUAL GRIT: One side features 120 grit (Dark Grey) for flattening coarse water stones with grit of 900 and below, delivering strong cutting action. The other side has 320 grit (Light Grey) for finer water stones with 1000 grit and higher, helping achieve a smoother finish.
