Over time your knife’s edge will begin dull and the blade’s finish will need to be polished. One of the most dangerous things in the kitchen is a dull knife. If the blade is not sharp enough to cut through, then you are more likely to be prone to accidents. There are several different tools to sharpen and polish your knives, but using the best sharpening stone will work in your favor.

A sharpening stone will also sharpen any other straight edge tool such as scissors or shears, swords, axes, machetes and razor blades.

A sharpening stone can be made up of many different types of materials which have a coarse surface to drag and pull the knife’s edge against. Sometimes the stone will also include a base to keep the stone in one place while sharpening a knife. If there is no base to the stone, then you can always place a damp towel under the stone while you are sharpening your knife.

There is also a specific technique for using a knife sharpener. Some stones may require you to lubricate them with water or oil. Others may have a finer grit to keep the sharpening accurate.

The grit of the stone is determined by how coarse the surface is. Grit can range anywhere from 200 all the way up past 8000. The higher the number of grits, the finer the surface will be. Finer surfaces are used to get as close as possible while the coarse surfaces are used to begin the sharpening process.

Using a sharpening stone can be difficult for a beginner. In case you may need a reference or crash course, use these instructions.

In this article, we will cover the different types of sharpening stones and what makes each type unique. We will also cover some of the best sharpening stones on the market today.

Types of Sharpening Stones

Water Stones

Water sharpening stones are usually made up of synthetic materials. These types of knife sharpening stones are the most widely used among professionals. They are very easy to use and need little to no extra care.

Before using a water stone, you will need to soak it in water for about 10 minutes. Once they are soaked, you are able to polish and sharpen your tools. Some stones only need to be rubbed with a little water before sharpening as well.

Oil Stones

Just like the water stone, the oil stone is also widely used. However, the stone needs to be rubbed with oil before sharpening, which can be quite messy.

Oil stones work the best with stainless steel kitchen knives, more specifically the filet knife.

Diamond Stones

A diamond sharpening stone is the king of sharpening tools. This type of stone can be used dry, with oil or water as a lubricant.

Diamonds are naturally sharp and very hard meaning they will cut fast and hard. It does not take much effort to damage a knife on a diamond stone if you don’t know what you are doing. The stone can overwork the edge of the blade very quickly by grinding off too much. It is recommended to use a diamond stone on severely blunt, damaged or dulled knives. This stone would not be the best knife sharpener for fine-tuning a carving knife.

Ceramic Stones

Ceramic sharpening stones are usually a double-sided stone, one side is coarser than the other. These stones can be used without any lubricant like oil or water but some think soaking the stone in water for 10 minutes will help soften up the stone, making it easier to get a finer edge.

These sharpening stones are some of the most popular among chefs to be used as a workhorse and sharpen all the tools. However, they need to be handled with care. If dropped, they could break very easily.

KING KW65 1000/6000 Grit Combination Whetstone

A Good Starter Model for the Beginner

This model of water stones is a step down from the previous model mentioned. However, it is also about half the price.

The stone is dual sided with two different grades of grit and comes with a hard-plastic base to hold it in place. The base does not have any rubber studs or slip resistance so you may find it hard to stay in one place while sharpening your knife.

This stone also needs to be soaked in water for at least 10 minutes to allow the water to seep into the pores of the stone which make it softer and easier to sharpen items. This does make the stone significantly softer which also makes it prone to chipping and damages.

  • Incredibly cheap price
Cons

  • No rubber studs or slip resistant material at bottom of the base to prevent movement when in use
