Doublesided Whetstone (5000 / 12000 grit) — precise, travelready sharpening for kitchen and professional use Key benefits Restores and refines blade edges: coarse 5000 grit reshapes and repairs worn or dulled edges; fine 12000 grit polishes for a razorsmooth finish. Ready for ‑hardness steel: effective on hard knives and tools where a consistent, sharp edge is required. Durable, consistent performance: made from white corundum for longlasting cutting surfaces that resist erosion through repeated use. Compact and compatible: edge length 100 x 25 x 10 mm fits most handheld knives and tools — convenient for home cooks, sushi prep, and travel. Features Dual grit design: red side = 5000 grit (coarse) for shaping; green side = 12000 grit (fine) for polishing and final stropping. Material: white corundum provides stable, even abrasive action and predictable results. Size: 100x25x10 mm — small enough to carry, large enough for most handheld blades. Usage: soaks in water for 15 minutes before use to ensure performance and reduce clogging. How it solves common problems Dull blades that refuse to cut cleanly — the 5000 side quickly restores geometry and removes chips. Burrs and rough finishes after coarse sharpening — the 12000 side polishes the edge to a smooth, refined cutting surface. Inconsistent stones that wear unevenly — white corundum construction resists erosion and maintains a consistent surface over repeated uses. Practical applications / use scenarios Home kitchen: sharpen chef's knives, paring knives, and utility knives for clean slicing, dicing, and chopping. Sushi and precision prep: maintain delicate, long edges on sashimi knives and other ‑precision blades for professional results. Travel and outdoor use: compact size makes it suitable for sharpening knives and tools while traveling, camping, or on the go. Quick use and care tips Soak the stone in water for 15 minutes before use; keep the surface wet during sharpening. Start on the red 5000 grit side to shape the edge, then switch to the green 12000 grit side to polish and refine. Rinse and dry after use; store in a dry place to preserve the stone's integrity.
