Put the whetstone / oil stone on a secure base / table. To flatten a stone, wet it with water or oil (depending on the type of stone) and rub the flattening plate evenly over its entire surface until all grayish evidence of previous sharpenings has disappeared. If you can’t tell if it’s flat, simply make a series of pencil marks across the stone, and then flatten until the marks vanish.

The alternative to a Correction Stone / Flattening stone, is a fairly inexpensive method. Start with a reliably flat surface, such as a piece of 12 ” thick glass (with edges ground smooth). Apply 100-grit wet-dry sandpaper, self-adhesive or adhere with our Spray Adhesive,  and rub the wetted (or oiled) stone over it until flat. Repeat with a few strokes on 400-grit paper to remove any coarse scratches. If you flatten your water stones / whetstones every time you sharpen and these stones show little wear, skip the 100-grit step.
