The Best Sharpening Stones to Hone All Your Dull Knives

The Best Sharpening Stones to Hone All Your Dull Knives

A lot of people have dull knives in their kitchen drawer because they're concerned they might ruin the blade by incorrectly using a sharpening stone. This is a very real fear, because using the incorrect stone or the incorrect method for the knife you are sharpening can compromise the edge and make it very difficult to ever get a decent edge again. But never underestimate the importance of a sharp edge – it's essential. So we want to help by showing you the different types of stones and how to choose the right stone for the type of knife you are sharpening.

What is the Best Way to Sharpen a Kitchen Knife?

Keeping your knives sharp will require that you have the right tools and the correct method to ensure great results. Even the best sharpening stones won't make you a master knife sharpener, but at least you'll be ahead of the game. 

Types of Sharpening Stones

There are different styles, sizes, and types of sharpening stones. Each one has specific uses and methods to use them correctly. Understanding the differences between the types of sharpening stones will help you to choose the right method for easily sharpening knives.

Whetstones

Whetstones are the most common type of knife sharpening tool and are widely available. But, not all whetstones are equal. There are both natural and synthetic knife sharpening stones. Natural stones are quarried, flat stones like Arkansas Stone or Belgium Blue Whetstones. Synthetic stones are the most common and go by names like Corundum and Carborundum to indicate the type of mineral used. Today, there is practically no difference between artificial and natural stones.

Water Stones

Water stones are a type of whetstone that uses water to work properly. Some stones are soaked in water before use while others are ready to use with just a splash. These stones frequently come from Japan and are often called Japan stones, though not all Japan stones are water stones (we know, that can be confusing).

Oil Stones

As the name implies, these stones need to be oiled when in use. The majority of man-made stones are oil stones, while some natural stones like Arkansas Stone may also work well. The type of oil can vary from stone to stone, and there are tons of opinions about which oil is best to use with an oil stone to get a razor-sharp edge.

What to Look for in Sharpening Stones

You'll want to select a whetstone that is the appropriate size for the task. You probably have noticed that most stones are six to eight inches long and two to three inches wide. This tends to be a good size for most kitchen knives. Too large or too small of a stone can create more work.

The most important thing to consider is the grit of the stone. Grit is typically shown as a number. Higher numbers indicate a finer grit that is more appropriate for finishing. Lower numbers remove more material, but can leave a rough edge. A good starting point for a sharpening stone that has two sides. This will let you repair damage like chips and blunt edges, then finish the blade to get a sharp edge.

What Grit Sharpening Stone is Best?

The best grit is the one that is appropriate for the job you are tackling. A fine grit with a high number won't effectively put an edge on a very dull knife, and you may end up damaging the stone. With that said, you can buy double sided sharpening stones that have 1000 grit and 3000 grit sides. This will give you the best options for sharpening dull knives and getting a good finish on the edge of your kitchen knives.

Are Diamond Stones Better than Whetstones?

The use of industrial-grade diamonds for sharpening knives is a relatively new tool for sharpening knives. These "stones" are actually pieces of steel that are glued to blocks of aluminum. The most common type uses small dots or buttons of concentrated diamonds, while some varieties are a sheet of diamond-coated metal.

Diamond sharpening stones come in a wide array of grits, but are often more expensive than artificial stone. The trade off is that they can last much, much longer. Diamond stones work great on most types of kitchen knives and are the superior choice for high-carbon stainless steel blades that are difficult to get a fine edge on with a stone. A diamond stone is a good choice for creating fine edges.
