It's hard work keeping your favorite and most used knives sharp. No matter how often or infrequently you break and use your knives, they will dull over time. And the knives you rely on most often dull the quickest. If you rely on a dull knife, you're using a less effective and potentially more dangerous tool, as dull knives can make cutting more difficult and less precise.

This is where the best sharpening stones come in. While knife sharpening is certainly a tedious task, it can be made easier with a quality, solid sharpening stone. Whetstones, also known as whetstones, are the perfect sharpening tool. Made from a variety of materials such as ceramic, aluminum oxide, or even diamond, some of these stones can restore the sharp, finely honed blades of your knives in no time.

The most common types of whetstones

Sharpening stones come in many different varieties. Just a quick search for whetstones will reveal thousands of options in all sorts of materials, shapes and grits. But there's an easy way to narrow down your options for finding a quality product: Decide what type of sharpening stone you want to work with.

There are three general and common types of whetstones. Whetstones are divided into types depending on how you use them to sharpen a knife: oil-based, water-based, or hard diamond-based. Learn more about each type below.

oil grindstones

Oil whetstones are one of the most common types you will find. Considered a "traditional" option, these stones are natural stones made of novaculite, aluminum oxide, or silicon carbide. To file your knife and sharpen your blade, use oil to lubricate the metal against these types of stones. Oil whetstones can offer different densities and create different finishes on your knife blades. Most leave a polished edge.

The main disadvantage of an oil sharpening stone is that this type of sharpening stone tends to cut metal more slowly than artificial stones. This slower cutting speed means you have to take more time working on your knife, which can be frustrating. Because oil is the necessary lubricant, the process can also be messy and more difficult to clean.

water whetstones

Water whetstones are another option, although they are a bit newer and growing in popularity. Like oil whetstones, water whetstones can be made from natural stone, but they can also be made from synthetic materials. The most common are synthetic water whetstones. Usually made from a type of aluminum oxide, these sharpening stones are abrasive but soft in their density. This makes water whetstones cut faster; You can easily mine old metal for quick sharpening.

While the faster cut is the biggest benefit of wet sharpening stones, lubrication is another benefit. The water is easy to wipe and clean after sharpening. However, there is a downside: water whetstones wear out quickly and tend to break more easily. This creates uneven surfaces on the whetstone, which can make sharpening knives difficult.


Diamond whetstones are the hardest kind you can buy. They are actually made up of small diamonds attached to a metal plate. These diamonds and their high hardness cut very quickly, turning blades from dull to sharp in no time. There are two types of diamond whetstones to choose from: monocrystalline or polycrystalline. Both last a long time, but the monocrystalline ones are the most durable.

Diamond sharpening stones sharpen at high speeds and stay flat even after many uses. There is only one downside - the cost. These whetstones are very expensive and an investment. However, you get a sharpening stone that will last a long time, which can be an advantage.

What to look out for when buying a sharpening stone

When purchasing the right sharpening stone for your particular knife and needs, you should consider two important factors. In addition to choosing the right type of stone, you should also take the time to think about the grit and durability of a sharpening stone.

The type of whetstone you choose will largely determine its durability. As we mentioned, some stones are just harder than others - diamond is the hardest material you can buy in a whetstone and it lasts the longest. Other options are softer and may not survive as long or through as many uses. Think about how many knives you use regularly and how often you sharpen them on your whetstone. If you use it frequently, you'll want a sturdier, more durable option.

The grit is crucial because it determines how well a whetstone actually sharpens knife blades. A lower number means you'll get a coarser grit - a number of 1000 or less is considered coarse and is best for extremely dull blades. A higher number indicates a finer grit, ideal for finishing, polishing, or creating a sharper edge. It's a good idea to have whetstones of different grits so you have everything you need to sharpen your knives.

The advantages of a sharpening stone

If you've ever seen the blade of your favorite knife dull and feel like there's nothing you can do to salvage it, there's a benefit to owning a whetstone. There are many benefits to these useful whetstones, but their greatest benefit is the ability to restore a good knife to its former glory. There's no need to rely on a professional or, worse, throw away the knife right away, as you can easily sharpen the blade yourself. Even if it's your first time using a whetstone, you'll love the benefits this stone brings to dull or imperfect knives.

  • Cost savings as you no longer have to replace dull knives or take them to a professional for experienced sharpening; And

  • $20 bis $40:For longer-lasting sharpening stones and a variety of different grit options, you can expect to spend anywhere from $20-$40. You're also getting slightly better quality at this price point.
