3-in-1 Manual Knife Sharpener

This manual knife sharpener features a compact 3-in-1 design with three distinct sharpening stages: coarse grinding using a diamond sharpening rod, repairing/maintenance using a solid tungsten steel disc, and fine grinding & polishing using a special ceramic rod. Dimensions: not specified in source; weight: not specified; total unit weight and exact dimensions are not provided in the original description. Constructed with an ABS plastic handle — heat-resistant, high-temperature tolerant, and impact-resistant. Each sharpening slot is lined with durable materials: tungsten steel (for the repair disc), industrial-grade diamond-coated rod (coarse stage), and precision ceramic rod (fine stage). The base includes a rustproof metal plate with integrated anti-slip rubber padding for stability on countertops. Designed for universal usability: suitable for right- and left-handed users thanks to its symmetrical ergonomic handle and non-slip grip. Compatible with a wide range of blade types including bone cutters, slicing knives, paring knives, fruit knives, and utility scissors. Operation requires no power — simply position the blade in the correct slot and draw 3–5 times for effective, controlled sharpening without risk of over-grinding or damage.
