A single stone of 120 grit and a combination stone of 1000 and 3000 grits come along with a stone holder all for a price of less than many other individual stones. The stones are 6 7/8" long and 2 1/8" wide. A flattening stone of some kind would be needed, but with economical options available in those, the overall price of this kit would still be low. This entry level set is a good budget minded option.
Begin by sharpening the knife from the front side. Sharpening is completed when the knife has an even burr. Only use a flat-surfaced stone to finish the back surface of the blade. Sharpen the blade from the edge to the spine. Do not sharpen at too great an angle between the blade and the stone. The stone used to finish the cutting edge of the blade should contact the edge evenly.
