Unique Design: The unique design of the whetstone set ensures that the dust generated during the grinding process will not affect the sharpening. Handles both rough and fine grinding jobs with ease. Reliable material: The whetstone is made of diamond material, which has good wear resistance and corrosion resistance. Due to the high hardness of the material and low loss during use, our whetstone set can be used for a long time. Easy to operate: Just place the knife on the whetstone and move it back and forth a few times while maintaining an angle of about 30°. You can add water or honing oil at any time when sharpening the knife, so that the lubrication effect during grinding will be very good. Stress-free use. General Purpose: The diamond whetstone is perfect for honing household kitchen knives, whether it is a household prop or an outdoor tool, you can use our whetstone to sharpen it.
