More info

This corundum sharpening stone is a great accessory for maintaining the blades of your kitchen knives as well as your outdoors knives, and other types of cutting utensils. Because using blunt blades is not only annoying but also unsafe, this natural stone can be a very useful accessory for your kitchen!

With a length of 23 centimeters, this stone is the ideal size for sharpening knives of different sizes. Moreover, thanks to its length, it is also easier to hold it whilst you sharpen your knives. Unlike most whetstones, this stone is for dry usage, which means that you do not need to add water or oil to its surface for using it. 

This natural stone is made of corundum (aluminium oxide). This material is extremely hard, and that is why it is rated 9 in the Mohs scale where 10 is the maximum hardness. Therefore, this stone is very solid and not so easy to break (as long as it is used under normal conditions, of course).

Discover all the natural sharpening stones available on and keep your blades always sharp!
