FAQs: Knife Sharpener Stones

What is the difference between a whetstone and a sharpening stone?

Whetstone is another term used for sharpening stones. Both terms refer to the same thing.

What grit is best for sharpening knives?

For repairing dull knives, you can use 1000-3000 grit. The finishing step of sharpening a knife's edge is done with 4000-8000 grit. You should use 4000 to 6600 grits when sharpening a knife for cutting meat.

Which side of sharpening stone goes first?

If you are right-handed, the first side of your blade should be sharpened. The remaining blade should be cantilevering on the stone. This will make it feel odd if you don't hold the knife handle in your dominant hand when doing the same thing on the opposite side.

How long does it take to sharpen a knife with a stone?

It would help if you always sharpen your knife when it is still sharp. To sharpen the knife, you will need only five to ten minutes on the stone. You will spend much more time if you wait until the knife becomes genuinely dull.

How often should you sharpen your knives?

The average knife should be sharpened once every two to three months, depending on its use. Sharpening is the process of restoring dulled or damaged edges. It requires a coarse abrasive, such as a stone, diamond plate, or belt.

How long should I soak a whetstone?

Before using rough and medium grit whetstones, be sure to soak them in water for 10-15 min. If you are using fine stones to sharpen, just splash some water on them. Fine stones can crack if they are left in water too long.

How do I know if my knife needs sharpening?

Gently move your fingertips along the edge of the blade. Sharp knives feel sharp when they have a distinct, well-defined blade. Sharpening your knife is a good idea if your blade feels dull or rounded.

Do you push or pull when sharpening a knife?

The right side of your blade should be sharpened first. Next, place the tip of your knife at the bottom end of the whetstone. Now, push the knife up to the top. Do this by pressing down on the blade with your two fingers. You can then release pressure by pulling the blade towards you.

Can a knife be too sharp?

While a knife cannot be too sharp, it can be sharp enough to be used for one purpose. For example, a knife can be too sharp for certain materials but not sharp enough to safely cut them.

Buyer's Guide: Knife Sharpener Stones

HOW TO CHOOSE THE RIGHT KNIFE SHARPENER STONE?

The knife's sharpness can be lost if it is used repeatedly, making it more difficult to use. A dull or chipped edge can also pose a risk to your health. That's why it is a good idea for your knives to be sharpened every now and then. And it's not easy to find the right knife sharpener. Sometimes it is best to go back to basics and use a tool that has been around for centuries to sharpen your knives, such as a whetstone.

If you want to get the best results, it is important to understand the purpose of each stone. However, if you don't have enough knowledge, you could end up with a knife not suitable for your needs. But first...

What is a whetstone?

Whetstones can also be called sharpening stones. These stones can be synthetic or natural and are used to sharpen knives and they come in different sizes and can be made of different materials.

You can transform the surface of the whetstone by running your knife's edges back and forth on it. The type of whetstone you use will determine whether the blade gets a polished or dull look.

Sharpening a knife using a whetstone can be simple, even though it might seem difficult. You must first ensure the blade is at an angle when rubbing against a stone.

These are some things to consider when buying a whetstone or knife sharpener stone:

1. Size

It will help if you are looking for the proper dimensions of the whetstone for your cutting tools. A small whetstone can make it more challenging to sharpen large knives, and the process can be dangerous and frustrating. A whetstone to sharpen kitchen knives should measure approximately 6 inches. A longer whetstone might be more suitable if you plan to sharpen knives that are over 8 inches in length.

2. Type

There are four types of whetstones available on the market. Each one has its pros and cons. Let's first look at the four main types of whetstones and their characteristics.

  • Water Stones

Water stones are one of the most popular whetstones. However, the stones must be soaked in water before they can be used. They are some of the most stunning whetstones available, but they can be very fragile. These stones can be very delicate if they are subjected to repeated drying and soaking. So, important to replace them once in a while.

  • Oil Stones

Before oil stones can be used, it is necessary to spray oil on their surfaces. This will ensure that the knife's metallic residues are removed when sharpening, and it will last longer. Oil can make sharpening more effortless, but it can also cause more work and take longer.

  • Ceramic Stones

If you're looking for a durable whetstone, a ceramic stone is an excellent choice because it is hard and brittle. It was designed to replace natural sharpening stones. Therefore, they don't require oil or water before use. However, it would be best if you cleaned it after each use. And once you are done, clean the whetstone's surface. It is essential to properly maintain a ceramic sharpening tool stone if you intend to purchase one.

  • Diamond Stones

These are the most expensive and valuable whetstones available. These whetstones, despite their high prices, are extremely popular. You can make diamond whetstones from either metal or plastic plates with tiny diamonds attached at the top. And there are two types -  The most popular one has holes in the surface, and the other one is continuous and has no gaps which are more expensive.

3. Grit

Many whetstones have a number on them. This number is probably not something you are familiar with but this number indicates the degree of coarseness or grittiness which means, the lower the number, the grittier a whetstone will be.

Each grade of grit is different and will sharpen your knife differently. Based on the number of whetstones, there are three types: coarse, medium, and fine.

  • Stones with a lower than 1000 point are known as coarse sharpening stones. These stones can be used to sharpen knives that are highly dull or badly damaged. However, these stones won't give your knife a shiny finish, so they are not recommended for use if your knife hasn't been sharpened.

  • Medium sharpening stones can have numbers between 1000 to 4000. The whetstone is the basic stone for sharpening with a 1000 number.

  • Whetstones are fine finishing stones, or stones with a number between 4000 and 8000. These stones can be used to create super-fine edges.

4. Quality, durability, price

A product should not be made of inferior materials or last for a long time. Therefore, you should carefully evaluate the price of a ceramic or diamond whetstone. However, longevity is not always determined by quality.
