Types of Knife Sharpeners Out There

Before you begin your hunt for the best knife sharpener, it is imperative to learn what your options are first. Here the various types of knife sharpeners you can find today:

  1. Sharpening Stones

These are flat, square-shaped stones that are used to sharpen the blade of a knife and many other cutting or slicing tools. They come in different levels of grits or finishes. Some are finer while others tend to be grittier. Finer grits are better if you want to slowly remove materials from the surface of your blade. The higher the number of the grit, the finer it is. How high the number of grit you will choose will depend on the kind of tool you are sharpening.

  1. Diamond Knife and Tool Sharpener

This sharpener is usually made from some form of composite or completely metal base. They are called by such a name because of the miniscule diamonds that are attached to the surface of the metal with the help of nickel-plating methods. What is great about this type of sharpener is that it does not cause the appearance of depression on the surface of the blade.

  1. Sharpening Steels

Also called steel rods, these are used for light honing purposes and for aligning metals. Many chefs use this in between cutting meats. There are sharpening steels out there that work in lightly sharpening blades.

  1. Electric Sharpeners

This kind of knife sharpener makes use of sharpening stones that spin in order to get the desired sharpness level. The right angle must be achieved in order to get the sharpness you are looking for. These are convenient to use but they can be difficult to control

Which of these types of knife sharpeners you should get should depend on your purpose and need.

Tips in Buying the Best Knife Sharpener

With so many options out there, it can be difficult to find a knife sharpener that will work well for your needs. Here are some tips to help steer you in the right direction:

  1. Consider the material.

The material of the knife sharpener will tell you a lot about the functionality of the sharpener. You can choose from different materials such as diamond flecks, carbides, ceramic and steel. Diamond flecks and carbides are typically utilized as an abrasive. Despite these materials having the same functionality, the diamond flecks are more expensive for obvious reasons. If you are on a budget, you might want to go for the carbide ones. However, you might want to spring for diamond flecks if you prefer something that doesn’t have an aggressive friction. This material usually creates a gentler sharpening process.

Ceramic and steel are generally preferred for honing. It goes hand in hand with sharpeners. If you need to clean up the cutting of your knife, this is definitely a good material to have.

  1. Make sure it does an even job of sharpening your knife.

You don’t want to end up with an uneven edge. That just isn’t great for creating even and aesthetically pleasing results. Steer away from those small and hand-held sharpeners because they can produce uneven results. They are also quite dangerous to use. These are typically included with knife purchases.

Always go with a stationary knife sharpener. It should sit on a stable manner on your countertop. It is also more ideal to get sharpeners with a cutting slot. You just run the blade of your knife through those slots. This results in more even sharpening.

  1. It should be easy and safe to use.

You definitely would want to avoid sharpeners that require holding them down with the use of your hands. It increases the likelihood of you cutting your fingers or palms. Look for those with ergonomic features and those that are easier to use. There are also those knife sharpeners that can be used no matter what hand you favor. Go for these ones if you have right and left-handed users in your home. Additionally, go for those sharpeners that can truly produce sharp results in mere minutes.

  1. It should come with a money-back guarantee.

The best knife sharpeners are those that come with a money-back guarantee. This way, if the sharpener does not do what it promises to do, you can always get your money back. This increases the confidence when it comes to buying the product.

  1. Go for durable ones that are resistant to cuts and nicks.

The sharpener itself should be made from materials that are resistant to damages. It should also be resistant to corrosion and other forms of wear and tear.

If you keep these tips in mind, you should be able to find a knife sharpener that will suit your needs and preferences better.
