Best Pocket Knife Sharpener

If you use a pocket knife regularly then you are well aware that they sometimes get dull and need to be re-sharpened. With so many sharpening tools on the market, it is hard to know what kind of knife sharpening system to use.

Curious about my favorite pocket knife sharpener?  Check it out here at Amazon.

This guide will give you the information you need in order to choose the system that will work best for you.

Before discussing how to select the best pocket knife sharpener, it may be useful to understand how to sharpen a knife. It is a relatively simple process. There are two steps involved…

How to Sharpen a Pocket Knife

Step 1: You must raise and remove the burr.

To form a burr, you grind one side till a burr is formed. Then to sharpen the knife, you evenly grind both sides of the blade until the burr is removed and the knife is sharp. Applying pressure to both sides of the blade evenly while grinding off the burr is important, if you want to obtain maximum sharpness.

Step 2: Consider the Angle of the Sharpened Blade.

The angle of the sharpened edge of the knife is important to consider as well. Both sides should meet at the apex of the blade and slope to each side evenly in order to produce the maximum cutting efficiency for each individual blade.

What Kind of Sharpening Systems are Available?

Each individual will have a preferred method of sharpening their own knives, but it is good for you to know that you do have different sharpening options available if you are a novice or if you want to try a different sharpening method. There are only four different kinds of knife sharpeners and each has its advantages and its disadvantages.

  • Use a knife Sharpening System

These are precision devices that are made to sharpen your knife for you so you can save some time and effort, but do not get knifes as sharp as some of the other systems do.

  • Using a whetstone to sharpen your knives by freehand

This knife sharpening technique relies on nothing except a whetstone and muscle memory to guide the blade across the stone to create a sharpened edge.

The Whetstone grinds the metal to make it sharp, but with this method there is no way to stabilize the angle of the sharpened blade. It is easier to cut yourself with a whetstone.

It also takes practice in order to develop the muscle memory necessary to do it properly. This is the most difficult knife sharpening system to learn to use, but is capable of getting knives the sharpest possible.

  • Other manual devices to aid sharpener

You can buy all kinds of devices to help you manually sharpen your knife, but they are not as effective as the whetstone and you are still doing all the work. This includes items such as belt sharpeners and wheels.

Pull through machines use two carbide tipped steel pieces that are precision welded at a specific angle. As you draw the blade through the device it is designed to sharpen both edges simultaneously.

Each piece of steel is set at a permanent angle and may not be capable of sharpening the blade effectively as other methods.

These devices are good for those who may be more prone to injury, children and those wishing to sharpen their blades in the field quickly and with minimal effort. These tools are easier and quicker to use than a whetstone.

  • Electronic sharpening devices

These devises are all electric or battery operated. They feature a V-shaped groove to slide the blade into to sharpen it. They are designed for speed, comfort and ease of use.

These are the most expensive of the sharpening systems, but also the easiest and most convenient. It is safe because it is hard to accidentally cut yourself using this system.

The disadvantage is that these systems still cannot get the blade as sharp as you can get it by using a whetstone, and they grind a lot of extra metal off the blade.

Freehand Sharpening Verses Using an Automated System

Freehand or Automated Sharpeneing Systems

Freehand or Automated Sharpening Systems. Which one suits you best?

Different people will argue that freehand knife sharpening is superior because you can get a sharper blade. Others argue that automated sharpeners are superior due to their speed and ease of use.

A few people compromise and use a manual tool such as a pull through which is similar to the way an automatic sharpener works, but is manually operated.

Ultimately it seems that the best method depends on the type of steel your knife is composed of, your comfort level handling knives and how much time and effort you choose to put into sharpening your blades and where you plan to use the sharpener.

The SunrisePro Knife Sharpener features a unique patented suction cup bottom so you can easily attach it securely to any smooth surface. Its marketing is mostly targeted toward the home consumer market segment, but it should not be a knife sharper that is overlooked by the outdoor enthusiast.

Simple and easy to use; just slide your knife through the sharpener two to three times for a razor sharp edge. The company holds a patent on this sharpening technology and they offer a 100% satisfaction guarantee if you are not happy with the performance of the sharpener.

  • The suction cup bottom would be useless if you are in the wilderness.
  • If you hold it in your hand your blade could slip and cut you.
  • It is made of plastic so it is not designed to endure rugged outdoor conditions.


My favorite knife sharpener is the Wicked Edge Precision Sharpener.  But it is pricy.  So the best of the best pocket knife sharpener has to be the Redi-Edge Tactical Pro Knife Sharpener Set.

Many people argue that using whetstones will give your pocket knife the best edge. While this might be true, it takes time to develop the muscle memory needed to use a whetstone properly to sharpen your knife.

Not everyone will be able to figure out how to sharpen a knife, if all they have is a whetstone.  The Wicked Edge and Edge Pro are both great systems, but they are not at all portable and the vise grip makes it difficult to sharpen smaller or thinner blades on these units.

The Sunrise Pro knife Sharper might have won if this was a review of a general knife sharpener, but its limited durability and usefulness in the field is questionable.

As a result, the Redi-Edge Tactical Pro Knife Sharpener set is the recommended best pocket knife sharpener available for most people.

It is designed to meet the needs of professionals, but it is simple enough to use that anyone can do it. This set is simple and quick to use.

It’s a great survivalist sharpener because of the notch for sharpening fish hooks and needles. It is very small, portable and extremely durable.

If you’re planning a skiing trip, or you just want a new skiing jacket, look no further than these recommendations.

    I own a fabrication shop, so I have a very good idea of the costs involved in producing items like the Wicked Edge Sharpener. The fact that you will end up paying over $600 for this very simple system is just ridiculous. While the ceramics are expensive, they are nowhere near THAT expensive, and the rest of the gizmo is just a simple stand, knife vise, and an angled, adjustable arm.
    It’s a shame that WE is so greedy, at half that price they would still be making a tidy profit (and if not, they need to contact me for a production cost analysis) and they would sell like hotcakes, to the average person…instead of a very limited market of professionals and preppers willing to spend that kind of money on a sharpener.
    The WES would be my first pick, if it were not for the cost.

    I own the redi-edge system, and agree it is a great SHTF system…but for an everyday sharpener I have to disagree. It is made to sharpen knives very quickly, essentially in a combat environment. While that sounds great, and it is- in a combat environment- the aggressive nature of the system eats knife blades like Pac-Man eats dots. Your Bowie knife will become a pen knife, very quickly.

    Great write up though, John- Thank you!
