The razorized dual functioning sharpening stone is an all purpose tool that restores and maintains knives, scissors and sharp tools. Razorized features two surfaces, a rough surface and a smooth one. If blade is dull start with the rough stone and finish with the fine one, otherwise the smooth surface will do. Begin with light steady pressure pushind the stone forward toward the cutting edge. During the forward motion, slide stone sideways as well until the tool is honed. Repeat on the reverse side of tool until desired edge is achieved. For best results, honing oil should be evenly spread over surface of stone. After use, stone should be wiped clean.
