Knives are among the essential kitchen tools but get blunt and dull over a period. Sharpening stones, also known as whetstones or water stones, are necessary to keep your knives sharper for safe and consistent slices. A sharpening stone is a rectangular block of stone used for honing the edges of the blades. A wet stone knife sharpener will bring back the shine and sharpness to your knives and effectively minimize the risk of injuries.
Sharpening stones come in different sizes and shapes and are made of various materials. Functional knife stones are a must in your toolkit to keep your kitchen knives in top condition. Here is a list of the best knife sharpening stones and tips to help you pick the right one for your kitchen.
Types Of Sharpening Stones
There are four varieties of knife sharpening stones.
- Water stones: Most widely used for sharpening kitchen knives, water stones are easy to use and reasonably priced. They are made of synthetic materials or Arkansas and do not need expensive liquids or oil as lubricants. Soak them in water for 10 minutes, and they are good to use.
- Oil stones: Made of silicon carbide or aluminum oxide, these stones can be expensive. They promise sharper edges and better shine and require the use of oil or different liquids for maintenance.
- Ceramic stones: Made of materials like aluminum oxide or silicon carbide, ceramic stones make better choices for final polishing or finishing. Ceramic stones are softer than water stones and oil stones but are best suited for sharpening deep blunt edges.
- Diamond stones: Diamond stones are the most expensive and effective sharpening stones as manufacturers use diamonds of industrial grade. They make a good choice for sharpening outdoor knives.

Frequently Asked Questions
1. How do I sharpen my knife using a stone?
The sharpening stone should be saturated in water or oil before use. You should follow the manufacturer’s guidelines before using the sharpening stone.
Place the sharpening stone on a flat and non-slip surface. Now hold the knife with the blade’s heel positioned at one end of the sharpening stone at an angle mentioned in the manual and cutting edge facing away. Use your other hand on the blade’s top side. Sweep your knife down and across the stone in a semi-circle shape. Repeat this ten to 15 times and then use the same method to sharpen the other side.
2. Is there a sharpening stone for a ceramic knife?
You can use water stones or diamond stones to sharpen ceramic knives. Using diamond stones is always a better choice because they are harder and require less time and effort to sharpen the knife.
3. For how long do I need to soak my whetstone?
You should soak the stone in water for five to ten minutes as water functions as a lubricant when you sharpen the blades.
