The only problem is that even you have the finest tactical knife at your disposal, it’s as good as useless if it has a dull edge. Unless you use your knife for buttering, it needs to be sharp to be effective, but every blade blunts over time so you should have a good knife sharpener around to stay on the cutting edge. This multipurpose equipment, unfortunately, isn’t really immune to the wear and tear of time. Fortunately, there’s a way out. Remember those good old days when some tradesman used to roam around with his bicycle with a grinding stone attached to it – he just had to scrub the blade against the stone at a particular angle and the knife is as good as new and razor-sharp.
Types of Knife Sharpeners
Even in this digital era, this technology has not become completely obsolete. However, the sharpening tools have definitely gone through dramatic changes to become high-tech, easy-to-operate, and highly efficient. These tools are generally divided into two main categories: Electric and Manual. The manual knife sharpeners are used mostly by the seasoned professionals or serious hunters because the manual sharpening technique requires a lot of patience and skill. An electric sharpener, on the other hand, is an efficient substitute for the manual ones, but mostly for the chefs and busy housewives who don’t have the luxury to spend hours on sharpening their knives.
Electric Knife Sharpeners
Automatic or electric knife sharpeners are fast and convenient to use and offer the precision of manual sharpeners. You don’t need to be a pro to use an electric sharpener; in fact, you just have to hold the knife across the tool and the tool takes care of the rest. Plus, they are so compact and easy-to-carry that so you can easily carry it around anywhere you want and it can also fit in your kitchen just perfectly. The tool resembles a box with a motorized grinding wheel. But for obvious reasons, electric sharpeners come at a higher price that their manual counterparts. But the time and energy you save in the process are worth the investment.
Manual Knife Sharpeners
The manual technique requires a great deal of your patience and certain skills. You take one wrong move and you can end up doing more damage than good. While there is no better way to get the perfect razor-sharp edge on your knife than with a sharpening stone, it’s a method that requires a great deal of practice to do it efficiently and correctly. Humans have been using this old-school technique for thousands of years and one still needs to practice for years to excel at the technique. There are a few fundamental kinds of manual sharpeners available in the market – sharpening stones, rods, and steel stones. Most people prefer using the rods for sharpening the knives because they are always readily available and require less expertise. They are also a significant part of a hunter’s gear since they are portable enough to be carried in backpacks.
Pocket Knife Sharpeners
If you follow the episodes of the popular series Man vs. Wild, you’d realize just how crucial a pocket knife is when you’re out in a dense forest or some deserted island for camping or hunting. A dull-edges knife could land you into some deep trouble in desperate circumstances. And carrying an over-sized, knife sharpener is not an option either when you’re traveling so much. Hunters have prior knowledge of knife sharpening with stones, but that too is a time-consuming technique and finding a perfect sharpening rod or stone in an unfamiliar land is too much of a hassle in itself. So for the same reasons, it’s wise to go for a perfect knife sharpener that’s compact enough to fit in your pocket.
The basic thumb rule here is grinding the blade against a hard rough surface at a particular angle. There is a common saying that iron cuts iron. Regardless of the tools being used, there are three basic steps involved while sharpening knives.
- Sharpening – This process involves removing all the unwanted material or chunks from the blade by setting the blade at an angle between 20 to 30 degrees against the stone or any other material being used for sharpening. This results in the blade tapering at the edges thus removing the dullness of the knife.
- Straightening – This process is done at a slightly lesser angle of about 15 to 20 degrees, which eventually makes the edges straight by removing the excess metal but not as much as in the sharpening process.
- Polishing – Finally, it comes the finishing part that ultimately gives the blade a mirror like smooth edge. It’s usually done by polishing the knife on a rotating cloth wheel which eventually helps the knife retain the sharpness for a long period of time.
Choosing the Best Knife Sharpeners – Factors to Consider
Finding the best knife sharpeners can take a little time and research, but if you do it correctly in the most efficient manner, you get a sharpener that not only keeps your knife razor sharp, but you might end up saving both your hard-earned money and your precious time on the long run. There are a few things to consider before making the run for finding the best knife sharpener.
The brand is one of the first things to consider before choosing any product – doesn’t matter if it’s your casual daily use shoes or a tactical knife for your little hunting expeditions – for the obvious reasons that it guarantees quality and reliability of the product. When you look for a good knife sharpener, it’s important to consider the brand. There’s a myriad of options to choose from when it comes to the brands. With a multitude of options available in the market, it’s more likely you’d find the best ones depending on your needs.
It’s important to choose between the different types as it helps narrow down other factors under consideration when choosing the right knife sharpener. An electric knife sharpener, as discussed earlier, is easier to use and provide more precision, while a manual sharpener needs a great deal of expertise and physical effort.
The material is one important factor to be taken into consideration because each sharpener is equipped with different materials in their abrasive wheels or surfaces; it can be diamond, steel, stone, ceramics, tungsten, etc. Most of the electric sharpeners leverage diamond-cutting technology for precise sharpening and they last for a long period as well.
Some sharpeners use a bevel angle which intends to determine the blade’s sharpness. Smaller the bevel angle, sharper the knife’s blade. Some manufacturers provide the bevel angle as a specification parameter in their catalog or product description. So make sure you have the smaller bevel angle. Many provide adjustable bevel angle which helps set the right angle depending on your needs.
When going through the various options when choosing the right knife sharpener for your hunting trips, it’s equally important to factor in the flexibility of the sharpener. While some units are capable of sharpening tools and scissors, many take the fun in sharpening serrated blades. This may not be the most important factor worth considering, but it’s worth looking into.

Knife Sharpener and Sharpening Technology FAQs
We’ve gathered a few frequently asked questions based on the guide and have compiled them here for your convenience.
What is the correct sharpening angle for my knife edge?
The answer to this question is not simple as it sounds. The sharpening angle of the edge depends on the type of knife, its particular use, and your abilities to re-sharpen. Let’s say you put a 20-degree angle on your knife, which means it’s sharpened each side to 20 degrees. This creates a total angle of 40 degrees. So when you’re talking about the angle on your knife, you refer to the angle at which you hold the knife to your stone. Choosing the right angle to sharpen your knife is essentially a compromise between the sharpness and the durability of the edge.
Is an electric knife sharpener bad for the blade?
Actually, some types of sharpener with conventional grindstones or abrasive belts can sometimes overheat the blade edge ruining the hardness and eventually the ability of the knife to retain its sharpness. But they also provide an easy way to sharpen most serrated kitchen and sports knives to a razor sharp edge. So the answer is both Yes and No.
How do I know if my knife is sharp enough?
To understand sharpness you must understand the definition of an edge. An edge, in simple terms, is the line of intersection of two surfaces. So a highly sharpened edge means the two surfaces are perfectly polished to form a very fine edge. Thus sharpening is achieved when it’s highly polished to that very fine edge.
Why do knives become dull?
All the loss of sharpness is a result of damage caused by contact with items you don’t want to cut, causing the very edge of the blade to begin to bend and fold away. Eventually, these areas break off and leave a dull edge. To keep the sharpness intact, these bends need to be regularly pushed back into shape before they further damage the blade. This can be done by frequent honing.
Which one’s better – a manual sharpener or an electric one?
While the old-school manual sharpening technology is far from becoming obsolete, the modern-day electric sharpeners are a fast and reliable way to retain that razor sharp edge to your knife’s blade. Manual sharpening requires a bit of patience and a lot of expertise, but the results are excellent. The electric sharpeners, on the other hand, are a fast and easy-to-use sharpening tool which doesn’t require much of the hard work or expertise. But both the techniques has its fair share of pros and cons. So it entirely depends on your needs and use.
