Things You Should Know Before Choosing A Knife Sharpener

With so many cheap knives on the market, many people tend to just throw out dull knives and just buy new knives. But there are a variety of reasons why more and more people are turning to knife sharpening to prolong the lives of their knives. Whether you just cannot afford to replace your knives or you found a knife (or set of knives) that you simply can’t bear to part with, knife sharpening is a cheap and effective way to maximize the usefulness of your knife or knives.

However, if you are new to knife sharpening, you may be hesitant. There is a lot of good information and quite a bit of bad information on the Internet, so here are some things that you should know before choosing a knife sharpener. Included will be the types of sharpeners; what sharpening and honing are; why sharpening is needed; when you should sharpen your knives; and how the type of knife may impact how it is sharpened.

Types of Knife Sharpeners

Knife sharpeners can really be categorized into three types: manual, electric, and whetstone.

Manual knife sharpeners are typically the cheapest and usually come in two or three stages. Each stage consists of v-shaped steel or carbon-based materials with varying levels of coarseness that you scrape your blade threw. Each time you run the blade through the coarsest slot, it rips material from the knife’s blade. The second and third finer stages are used to sand out the jagged rips caused by the first stage. Manual sharpening is quick and easy, but it is very traumatic on the blade and should only be done sparingly.

Electric knife sharpeners take manual sharpening to the next level by using spinning wheels to expedite the manual sharpening process. Electric sharpeners also take some of the guesswork out of sharpening by utilizing blade guides that ensure that the blade is sharpened at a straighter and more accurate angel. But like manual sharpeners, this process is quite traumatic on the blade.

Whetstone sharpening is the preferred method of knife sharpening, but it can be time consuming and takes a little practice to do properly. Whetstones are blocks of coarse, gritty stone that evenly sharpens your knives without tearing away too much of the blade’s material. With the proper technique, whetstone sharpening will significantly increase the life span of your knives, spare the material for future sharpening, and keep your knives exponentially sharper than any manual or electric sharpener can.

Difference Between Honing and Sharpening

The terms honing and sharpening are oftentimes used interchangeably, but the reality is that they are two completely different parts of the sharpening process. It doesn’t help that some knife sharpening products are mislabeled as hones when they are actually sharpeners. But by knowing the differences between the two processes, you can apply your knowledge to better sharpen your blades and prolong their useful lives.

Sharpening knives means that you are using a coarse material to grind material from the knife. With manual and electric sharpeners, this step is usually completed in the first, coarsest stage. When using whetstone, coarser stone between 200 and 1000 grit are recommended. During sharpening, the goal is to make the bevel (the knife’s vertical angle of the cutting edge) as thin as possible, which leaves it razor sharp. But sharpening leaves the blade’s edge jagged and rough.

Honing is the process of refining or polishing the bevel. Honing is conducted in the second and third stages of manual and electric sharpeners using finer sharpening materials. When using whetstone, additional blocks of 1,000 to 10,000 grit are required. Although some material is still stripped from the bevel, it is considerably less material and much less traumatic on the blade. To summarize sharpening sharpens and honing polishes.

Why Do You Need to Sharpen Your Knives?

This may seem like a silly question, but it can actually be quite complex. Some people choose to sharpen knives because they can’t afford new knives or choose not to spend money on new knives. There are many budget knives available, but they are usually made of inferior materials that wear out quickly. If you total the amount of money spent on replacing cheap knives with the price of a good quality set of knives, you will usually see that you save money with the quality knives over time.

Other people choose to sharpen knives because they have found a knife or set of knives that they really like and don’t want to replace them. Using proper sharpening techniques and whetstone, you can keep quality knives razor sharp longer than you will live, even with frequent use. You may choose to pass your favorite knife or knives to your children and with proper care they may be able to pass it down to further generations.

There are even some people who choose to learn how to sharpen knives as a form of self-reliance. There may come a time when quality knives may be hard to come by, so being able to sharpen them alleviates the need to find, purchase or make new knives. Outdoorsmen, hikers, backpackers, and campers also use the skill of sharpening to keep their tools effective while out in the field.

How Do I Know When My Knives Need Sharpening?

There is not really any scientific method to determining when you should sharpen your knife. A basic rule of thumb is to sharpen it whenever you determine that its performance has deteriorated to an unacceptable level. Simply put, if you think it is dull, it probably is.

Some people recommend different methods to testing the sharpness of a knife. One test is known as a tomato test. In this test, you test how much resistance you experience while cutting through a ripe tomato. If the blade is dull, you typically will experience the most resistance while trying to break through the skin of the tomato. If the blade is particularly dull, it may even feel like it is ripping through the skin. A well-sharpened knife will slice threw a tomato with the same ease as it would through butter.

Another popular test is to cut through cold meat. As the blade gets duller, it will encounter greater resistance and it will be more difficult to cut through the meat. A finely sharpened knife can easily penetrate through layers of flesh. However, you should never push the blade of the knife against your skin even if you suspect the blade is dull.

What Type of Knives Will You Be Sharpening?

There are many different types of knives, but ultimately the process of sharpening them remains the same. Yet, there are some variables that will dictate how coarse your sharpening material (whether manual, electric or whetstone) needs to be and how many times you will have to scrape the blade on the material. The two biggest variables are the type of blade material and the thickness of the knife.

Blades are designed using dozens of different types of steels, metal alloys, composites and other materials. The type of material determines how strong the blade is, how resistant it is to corrosion it is, and how brittle the blade among other things. The material of the blade will dictate how coarse your sharpening material must be to grind away the knife’s material. This will require some knowledge of the knife and some research of materials on your end. Furthermore, thicker blades will require coarser materials and more effort to sharpen than thinner knives.

One final consideration is serrated knives, or knives that claim to never need sharpening. Serrated knives are designed like saws. Although they can still cut while the blade is dull, they rely on their teeth to rip through what they are cutting. If the teeth become bent, they will need to be repaired. There are sharpeners designed for serrated knives, but you will need to research whether a serrated knife sharpener will be effective or if you will have to return the knives to the factory for repair.

Knife sharpening is an easy, cost effective, and fun way to spare the life of your knives.
