This is the best sharpening stone of its kind for the money. It's conventional wisdom that proper sharpening requires starting from a coarse grit abrasive to remove blunted or mechanically fatigued metal before sharpening and polishing with progressively finer grits, however, in my experience it is generally less time consuming and more effective to use this stone for general purpose sharpening unless abnormally great care is needed. This stone is aggressive enough to produce noticeable results quickly yet it is fine enough to still be useful in refining knife edges to push cutting performance levels and polishing a knife's bevels to mirror like reflectivity (albeit deeper scratches in the metal will be visible unless you have successfully gone through the more traditional low to high progression of grit levels). This can be the only sharpening device for knives you will need unless you are in the business of making knives or sharpening large numbers of knives on other people's behalf.
I bought these knives based on the reviews on the web. As you can all see, the reviews are very positive. So, I purchased these with VERY high expectations. I was reluctant based on how expensive these knives are. After using them now for several months I am blow away by the quality of these. It has changed my whole view of how important great knives make to my meal preparation. I can say without reservation that these knives are a bargain. These are a great investment in yourself and your family. Man, are these sharp! Recommend these without reservation.
Four hundred million years ago in a small geographical region of Central Arkansas, now part of the Ouachita Mountains, nature began the creation of a sedimentary rock formation composed of microcrystalline quartz called Novaculite. The word Novaculite comes from the Latin word novacula, meaning razor stone. Novaculite is a recrystallized variety of chert. It is the stone material from which whetstone and oilstone sharpeners are made.
