DualSided Functionality One side uses 300 grit for coarse sharpening and the other side uses 400 grit for fine tuning. This design lets you go from reshaping rough edges to finishing with a single tool. Fast and Smooth Sharpening The optimized grinding groove supports quick, even sharpening, helping you achieve a sharp edge efficiently with less effort. Storage Friendly Includes a lanyard rope and an integrated hanging hole for easy storage, keeping your workspace organized and clutter. Use scenarios Kitchen knives: Quickly restore a dull blade with the 300 grit side, then finish with the 400 grit for clean, precise slicing. Woodworking tools: Sharpen chisels and plane blades in two steps—coarse shaping with 300 grit and fine tuning with 400 grit for a crisp edge. On the go or in the : Hang on a pegboard or use the lanyard for portable sharpening during fieldwork, camping, or tidy workshop setups.
