Best Knife Sharpener Reviews 2018: Top 5+ Recommended

I think you will agree when I say: Knives are one of the most essential cutting tools in the kitchen area.

From slicing fruits and veggies for snack to cutting, dicing and mincing ingredients for dinner, knives will always be at your service. If you have a passion for cooking then you might even have a collection of knives displayed at the corner.

However, like all things, knives are not always at their best. Being at your mercy every day can cause them to become dull and frustratingly useless. The ingredients’ acidic contents can corrode the edge’s steel and continuously gets blunts as it hits the surface of the cutting board. It does not matter if your knives are cheap or expensive, the time will still come where you will need to bring them back to life. And the best way to revive them is through the service of knife sharpeners.

How do knife sharpeners work?

Knife sharpeners have one job to do. Bring a dull blade to its sharpest glory. Even though there are many different types of knife sharpeners out there, all methods will follow the same process type to achieve the end goal. 

The metal blade is rubbed against an abrasive surface in which microscopic amounts of metal is removed and creates a sharper and thinner edge. Moreover, some knife sharpeners are able to create an exact angle. And you need to understand that not all knives have the same angle. 

For instance: Most Asian style kitchen knives have a 15° angle while its Western counterparts have a 20° angle. 

Busting the Myth “Dull knives are safe knives” 

If you think that dull knives are safer just because they are, well, not sharp, then you are putting yourself in danger. Dull knives cannot easily cut your fingers, however, they always have “accidental” ways to do it. A dull knife has the tendency to slip on whatever ingredient you are cutting and injure you right away. Keep in mind that a dull knife is still a knife. 

Moreover, a dull knife makes your work harder. You will need to exert more force in cutting and using extra force on a dull knife does not guarantee that it will cut through and can cause to slip “accidentally” into your fingers and with much force, thus becoming more dangerous than sharper ones.

Lastly, dull blades need more cuts with lesser precision. So, how is this dangerous? It is just a case of averages over time: more cuts means more chances to actually cut yourself. So, do not disregard your safety and sharpen your knives in order for it to do the job properly.

Sharpening VS. Honing

Despite being interchangeably used quite often, sharpening and honing are actually different. They also differ in terms of actions. Honing is the process of straightening bent or curved edges while sharpening is the process of removing microscopic metallic particles from the edge in order to create a new cutting surface. But, they do have one goal: That is maintaining the edge of a knife.

When a knife’s edge seems to be dull, the first process to use is honing. Typically, Professional chefs hone the knife before use. If honing fails to give a good cutting performance, sharpening will be used.

When to sharpen a knife?

The time when to sharpen a knife depends on 3 factors: hardness of blade, the frequency of usage, and metal type of the blade. The standard rule: high-quality blades need to be sharpened once every 4 months.

If used heavily an inexpensive knife might need sharpening every fortnight. High-quality blades, on the other hand, can be sharpened once a quarter under the same usage.

Types of Knife Sharpener in the Market

When it comes to knife sharpener there are two basic types available on the market:

#1. Electrical Knife Sharpeners

The modern era presents electrical everything. And the process of sharpening knives is not an exception. Electrical knife sharpeners can do the trick in just a nick of time and it is probably is the most effective way to sharpen a knife.

Electrical knife sharpeners have two to three phases that use the force of electric in order to create a resistance for the blade to sharpen against. First, the knife is sharpened with a coarse grit, which is great on knives with very blunt edges. Then onto a finer, smoother grit that finishes the job and ends with a very sharp blade.Electrical knife sharpeners have two to three phases that use the force of electric in order to create a resistance for the blade to sharpen against. First, the knife is sharpened with a coarse grit, which is great on knives with very blunt edges. Then onto a finer, smoother grit that finishes the job and ends with a very sharp blade.

Moreover, most of these knife sharpeners have a guide that lets you know if your knife is properly positioned to the parts that need sharpening.

Pros

  • Ideal for commercial use
  • Does the job to the highest standard
  • Much, much faster way to sharpen knives.
Cons

  • Not economical for people who use their knives occasionally
  • Very, very expensive

#2. Manual Knife Sharpeners

As its name implies, manual knife sharpeners need a little sweat. However, high review rates for the best knife sharpeners in the market point to the manual option. Why? Well, because they are effective, very easy to use and a lot cheaper than electric versions. For a regular kitchen, this type of knife sharpener is ideal and can handle a small family who cooks regularly but not excessively.

Manual Knife Sharpeners can be broken down into 3 more categories:

#2.1. Sharpening Stones

We have the old style sharpening stones. These are versions of manual sharpeners, that are rectangular, 1-inch thick solid slab or block or diamond, whetstone, ceramic or other sharpening materials. Before use, sharpening stones need to be dampened with water first. They are available in a variety of sizes and shapes with some that are designed in few shapes for complex sharpening or flat for flat edges.

When opting for sharpening stones, the best one is made of 3 materials: Silicon Carbide, Aluminum oxide, or Novaculite. These sharpening stones are flat, abrasive stones which work by grinding the steel of the blade to it and then honing afterward for the final sharpness. This type of knife sharpener is also great for pocket knife sharpeners because of its small and compact size.

Nowadays, there are various composite and artificial sharpening materials for sharpening stones. Here are some of them:

  • Natural Stone
    In ancient Japan and Europe, natural stones are the most common form of sharpening stones.Good quality natural stones are much more effective and satisfactory compared to other stones but these are more expensive due to the fact that there are few operative mines. It gives a lasting edge because of the various grits that lead in serration of different sizes, exhausting at a random pace. Consider using natural stones for single bevel Japanese knives.
  • Ceramic Stone
    This type of sharpening stone is a modern alternative to natural stone. Ceramic stones are manufactured using minerals but with less porous texture because you will need to soak it in water for a few minutes in order to saturate the pores. Ceramic stones are great for single-edged knives.
  • Synthetic Stone
    Gaining popularity, synthetic sharpening stones are usually made of fused aluminum grit perched in resin. Several synthetic stones demand to be soaked in water before use, however, there are those that only requires a splash. Synthetic stones work for western style steel knives but also works with traditional single sided Japanese steel.
  • Diamond Stone
    Not your typical diamond rock on a wedding ring, this diamond stone has durable diamond materials with metal plates that hold the microscopic diamonds. This type of sharpening stone has a flat surface and does need oiling. Moreover, it very easy to clean and only needs a wire brush in order to discard the small particle and shavings.
    Diamond sharpening stones are becoming popular due to their ability to prevent a recession in the sharpening surface and cuts quickly.
  • Oil Stone
    Oil sharpening stones are the most affordable sharpening stones out there. However, it has a slower cutting rate and the oil can be quite messy. But if you want an extremely fine finish, nothing beats oil stones. 
  • Water Stone
    If your priority is easy cleanup and quick cuts, then water stones are better option than oil stone. However, the aluminum oxide (its construction material) is very soft and abrasive that can cause for the stone to wear away much faster than others. So you may need to flatten it often.
Pros

  • Effective at sharpening regular knives, even the smaller ones
  • Easy to use
  • Low cost and easily available
Cons

  • Not ideal for very large knives
  • Needs a manual elbow grease
  • No guides or grooves which can be dangerous for first time or nervous users

#2.2. Manual Pull-through Sharpener Systems

Manual pull-through sharpeners work by pulling the blade in order to draw the blade on the grinding wheels or the sharpening sections. Most of these units have different grits in one.

Common units have coarse and fine stages, but there are those with up to 4 stages. However, pull through systems have a fixed angle that only has limited flexibility. This sharpening system is something you can use if you do not have the time to guess the right sharpening angles or master your sharpening skills with a stone.

Pros

  • Simple to use
  • Low maintenance
  • Gives a uniform angle
  • Compact
  • Sharpens blade of common length
Cons

  • Expensive
  • Not applicable for machete knives

#2.3. Sharpening Steels

Sharpening steels, otherwise known as butcher’s steel is actually intended for honing knife blades. It has the ability to sharpen knives but it is quite less effective than others.

Sharpening Steels

Sharpening steels are inexpensive, very easy to use and easy to store. This is a tool which has one or more several ruts with different levels of abrasive surface or grit within them. To sharpen your blade, you simply rub your blade forwards and backward against it.

Pros

  • Simple
  • Flexible
  • Low maintenance
  • Can sharpen any blade of length
Cons

  • Time-consuming
  • Requires practice in order to sharpen at a constant angle

1. Safety

2. Need for Speed

Do you need to sharpen your knives in a few seconds? Or you are not much in a hurry? Different knife sharpeners work at different paces. If you want something that does the job quickly, go for electric or pull through sharpeners.
