Sharpening Stones – Getting Started

There are a lot of varieties of sharpening stones in the market and finding the best one will depend on your needs and preferences.

Everyone wants to get stones that will provide them with the most practical use. You would not want to waste money on something that you will probably need to replace later. When it comes to sharpening tools and knives, you need a stone that can be used as a foundation for your future needs.

However, there are a lot of options available for you, and you often find yourself wondering where to start in your quest of finding the best sharpening stone. To help you narrow your choices, here are some factors that you need to consider when looking for a sharpening stone.

Grit – How to Choose the Best Grit for Your Sharpening Needs

The grit is the most critical aspect of a sharpening stone. Dull knives need a coarser stone to get it back into shape. Likewise, you will also need a finer grit stone to put a very sharp edge on an already sharp knife.

If your knives are already in good shape and just requires a touch-up, you need a finer grit stone may just be enough. However, if your knives need extra care, you need a coarser stone.

If you need both grits, you can always go for a combination sharpening stone. This tool often comes in a two-sided form, with one side coarser and the other side with a finer grit stone.

When looking into the grit of a sharpening stone, you will often see different numbers. These numbers refer to the size of the grit. Large numbers often indicate finer grit while lower ones indicate coarser grit.

For instance, when you have a two-sided sharpening stone with 400 and 1000 grit. The 400 grit is the coarser stone that is used for sharpening the tools while the 1000 grit will be used for refining the tool’s edges.

Size – Finding the Right Size

Yes, the size of the sharpening stone also matters. In fact, the size of the sharpening stone you buy will mainly depend on the size of the knives that you plan on sharpening. If you are looking forward to honing large knives, you will need a large stone.

However, if you are using the sharpening tool on your average kitchen knife, you will need a stone that measures about 7 inches long and about 2 ½ inches wide.

Type of Stone – Which Type is Best?

The type of stone refers to the material the stone is made with. There are different types of sharpening stones, including natural stone, ceramic, diamond, and synthetic.

Diamond sharpening stone


This is a popular choice due to their ability to cut fast. This is ideal for professional craftsmen, as sharpening tools using this stone can cause a lot of damage if done in the wrong way. Also, since they are slightly sharper, the stone can leave deep scratches on the blade, which will require aggressive polishing. This stone can be used with or without any lubricant.

Natural Stones


Natural stones are considered one of the earliest form of sharpening stones. This type of sharpening stone is often expensive and comes with random grit sizes that provide you with a long lasting edge.

Ceramic Sharpening Stone


This type is considered the early replacement of natural stones. They need to be soaked for about 10 minutes or more before using to ensure that the pores of the stone are well saturated.

Synthetic Sharpening Stone


Synthetic sharpening stones are made of white fused aluminum grit which is suspended in resin. Some stones require a brief soaking in water before it is used while others just need a splash of water. You can find a variety of stones under this category.

Ease of Use

If you are looking for the best sharpening stone, you would want something that you can efficiently use.

Learning sharpening technique needs focus even without having to worry about the stone constantly. You may want to purchase a sharpening stone that does not require frequent flatting, cleaning or soaking or a stone that takes a longer time to create an edge.

If you are a beginner in this field, you should purchase a stone that is easy to use.

Water vs. Oil – Which is a Better Option?

All sharpening stones require either water or oil to act as a lubricant to sharpen tools. Most people prefer water stones as they are easier to use and less messy. Also, they are readily available and will not go rancid as oil does.

If you opt for a water stone, you may need to soak the stone in water for about ten minutes or more or splash water on the stone right before you begin the sharpening process.

It is essential that you read the manual of the sharpening stone that you buy to make sure that you use the right lubricant. Also, you should be mindful how you apply the lubricant as the incorrect application can cause the stone to chip or break.
