Whetstones, also known as sharpening stones or "wet stones," are indispensable for maintaining the sharpness of steel tools, particularly knives. The term "whetstone" comes from Middle English "whetston" and Old English "hwetstān," meaning "sharpening stone." Contrary to popular belief, "whet" means to sharpen, not to wet (soak in water before use). Using the right whetstone sharpener can keep your blades sharp and effective for years. These stones work through grinding and honing, ensuring that your knives remain in top condition.

  4. Polish the Edge: Use a finer grit stone to polish and refine the edge to a mirror finish.

How Do You Care for Whetstones?

Clean and Store Properly: Rinse your whetstone after each use to remove any residual slurry and allow it to air-dry completely before storing.

Keep Your Stone Flat: Regularly flatten your whetstone using a flattening stone or fine-grit sandpaper to prevent it from wearing unevenly, which can cause undesirable curves on your blade.

Whetstone vs. Honing Rod: What's the Difference?

A whetstone sharpens the blade by grinding away metal to create a new edge, while a honing rod realigns the blade's edge without removing metal. Honing rods are not recommended for Japanese knives due to their rigid steel, which can chip.

Professional chefs often use double-sided stones because they offer multiple grit levels in one stone, providing efficiency and versatility in sharpening.

Best Whetstone

For kitchen knives that haven't been heavily used, start with a medium-grit whetstone and finish with a fine-grit whetstone. The 1000/6000 grit whetstone is considered the best and most commonly used. Begin with the 1000 grit to sharpen and restore the edge, then use the 6000 grit for a refined finish. The stone creates a slurry for optimal sharpening, with a stable base and anti-skid feet for safety. Angle guides ensure precision, and they can be removed for freehand sharpening. Cleanup is easy with increased water control.
