Double side design Portable Diamond Folding 5 Inch Sharpener 400/600 Grit has a coarse side and a fine side. Coarse 400 grit (38 Micrometres) for quick edge setting; extra fine 600 grit (23 Micrometres) for honing. Diamond whetstone and ABS handle are non-slip and lightweight. The honeycombed, intermittent sharpening sides allow you to sharpen your knife faster by collecting built-up metal shavings. The stripes are on the handle, which can play an important anti-slip role. The concave-convex design at the end of the handle prevents the handle from being dislocated during use and avoids pinching your fingers. The scalloped and folded construction provides great protection for the stones from damage. The folding sharpening tool is small but powerful. It fits perfectly in your pockets and bags. [WIDE APPLICATION] Metal knives, ceramic knives, scissors, outdoor tools, garden tools, farming tools. A must have for your camping or home kitchen.
