Lansky Tri-Stone Benchstone Sharpener - Lansky delivers the most versatile 3 Stone Sharpener available， Combining 3 of their best stones: Diamond， Alumina-Oxide， and Ceramic.  The result is a stand-alone， high-value sharpening center that will do it all， with better versatility than other similar products and last longer doing it. All sharpening surfaces measure 2in x 6in.

• The continuous diamond surface (120 grit) will repair and re-profile extremely dull or damaged blades.  This is not to be used every time， only on blades in need of serious repair or re-profiling.
• The long lasting Alumina-Oxide surface (280 grit) is where most your touch-ups will occur， before polishing it off with the ceramic side.  This is most comparable to a traditional sharpening stone， producing a working-edge that is adequate for most cutting tasks.
• -The Ceramic surface (1000 grit) is used for sharpening and finishing.  This is what will turn a micro-serrated edge into a smooth， shaving-sharp， cutting edge.  The type of edge you can confidently brag about. 
• The sturdy plastic base boasts a wide footprint with low-profile and non-slip rubber feet giving the Lansky Tri-Stone Benchstone greater stability， resulting in greater user satisfaction.
