| Our verdict | At under ten dollars, this 400/1000 stone offers the most basic entry point into freehand water stone sharpening. It is adequate for working dull blades back into functional kitchen shape. Given the low price, the stone is soft and will require frequent flattening to remain useful. | At ten dollars, this combination stone targets coarse bevel repair and basic working sharpness. The 400 grit handles chips and dull profiles, while the 1000 grit leaves a serviceable culinary edge without fine polish. The binder is likely soft, meaning users must monitor surface flatness closely. |
