Double-Sided Foldable Sharpening Stone

This compact sharpening stone measures approximately 12.5 x 3.25 x 1.6 cm when folded and extends to 23 cm when opened. It is constructed from crystal abrasive material bonded to a durable plastic body, ensuring long-term structural integrity and consistent performance. The dual-grit surface features a coarse side (360–400#) for efficient edge restoration and a fine side (600#) for honing and refining sharpness. Its foldable hinge design allows it to be securely closed for protection and portability — easily fitting into pockets, tool rolls, or camping kits. Ideal for maintaining knives, garden shears, scissors, and other edged tools during outdoor activities, kitchen use, gardening, or light industrial tasks.
