What do onions and Disney movies have in common? They make you cry! We probably can’t do anything about the movies, but a sharp knife can keep onions from making you cry. The KME knife sharpener is just one tool you can use to slice onions without tearing up.

There are many different knife sharpeners on the market, and they all have different features and properties. Some knife sharpeners are manual, and others are electric. You can also use stones with different grits to sharpen your knives.

If you’re ready to cut an onion in peace, you need a good knife sharpener. Is the KME knife sharpener your perfect match?

What Is the KME Knife Sharpener?

The KME knife sharpener is a knife sharpening system. This system comes with everything you need to make a dull knife very sharp. The KME sharpener is a manual rod-guided system with a controlled angle. The small set is portable, but it offers many unique features.

Knife specifications

The KME Knife Sharpener System comes with many accessories and tools to sharpen your knives. You will get four different KME Gold Series diamond hones, a one-ounce water bottle, and a cleaning cloth.

The system also includes instructions, a hardshell case, and the KME base. You can sharpen your knives easily with the rotating blade clamp and spherical rod guiding system.

You can adjust the angle from 17 to 30 degrees, and the clamp is lined with neoprene to avoid scratching your blades. The standard vise does interchange with other KME jaws that you can buy separately.

The grip and stone holder is cherry wood, and you can use the stone holder for quick stone changes. You can fit all of this in the small hardshell case.

Customer reviews

The KME Knife Sharpener System has an average rating of 4.5 out of 5 stars. One customer defended the knife sharpener’s high price by saying it sharpens knives just as well as other more expensive systems. Another customer said that while the sharpener is very good, it can scratch the sides of the blade.

A third customer said that the system is perfect for people who don’t know how to use a freehand knife sharpener. Overall, customers love the KME Knife Sharpener System, even with its high cost and few included stones.


The KME Knife Sharpener System costs $200 to $220. It is more expensive than some other knife sharpeners, but you do get a lot of accessories with the kit.

The four included stones have different levels of coarseness, and the rod guide is great if you’ve never used a freehand sharpener before.

How It Compares

The KME Knife Sharpener System is a manual sharpener, so we had to do some digging to find comparable products.

Many knife sharpeners are electric, so while the price is similar, you can’t actually compare the two. As a manual sharpener, the KME system does have competitors with worthy products.

How we reviewed

We found similar knife sharpeners, but we had to do some research. Many knife sharpeners in the KME’s price range are electric, so they aren’t really comparable to the KME Knife Sharpener System. After some digging, we found a few similar knife sharpeners to compare.

What to look for

When you go shopping for a knife sharpener, you want to make sure you are getting a high-quality sharpener that will suit your needs. While electric sharpeners are easy to use, manual sharpeners keep your blade sharp for a longer period of time.

There are also stones with different grits that you can use to sharpen knives. Coarser grits are perfect for damaged knives. You can use a medium grit to sharpen a dull knife. Fine grits work best to refine an already sharp blade.

If you’re on a budget, you will also want to look at cost before you choose the perfect sharpener. This can get tricky because there are cases where you get what you pay for. If you’re looking for the best of the best, a higher price is probably worth the investment over time.

KME Knife Sharpener Pros and Cons

The KME Knife Sharpener System has many amazing features, but there are some downsides that you won’t face with other sharpeners.

The pros

It’s easy to use. Many customers love how easy it is to use the KME knife sharpener. Some manual systems can be difficult for beginners, but that’s not the case with KME. The knife sharpener comes with instructions, so you can easily learn how to use it properly.

Everything’s included. This knife sharpener comes with all of the tools and accessories you need to sharpen knives. You don’t have to worry about buying stones, a base, or anything else you might need.

If this is your first sharpener, you probably don’t know what you need to get. The KME Knife Sharpener System solves that problem by giving you all of the essentials.

You can choose from different grits. Depending on how sharp you want your knives, you can use stones with different grits. You get four stones with the sharpening system, and you can purchase other ones separately if you choose.

It’s made in the United States. Many companies outsource their production overseas, but KME manufactures all of their products in the US. When you buy from KME, you can trust that it wasn’t made in some random factory in a foreign country.

The cons

It’s pricey. The KME knife sharpener costs $200 to $220, so it’s not for the faint of heart. If you’re on a strict budget, this knife sharpener might not be worth it.

Casual users won’t need all of the features and may prefer an electric sharpener. If you want a serious knife sharpener, it is worth the cost.

You can’t store it without disassembling it. One customer said that you can’t store the knife sharpener in its case without taking it apart.

This is fine if you only sharpen your knives occasionally. If you want to sharpen your knives quickly on a regular basis, you will have to leave it out of the case.

It’s manual. As previously mentioned, the KME knife sharpener is a manual system. If you don’t want the hassle of sharpening knives manually, then you should consider an electric knife sharpener.

Some manual systems take time to learn, which can be a problem if your knives are in dire need of sharpening.

The packaging isn’t consistent. A couple of customers reported that their KME Knife Sharpener System didn’t include all of the necessary parts. One customer didn’t receive the polishing cloth, and another didn’t receive the base for the system.

The Sharpest Tool

After looking at all of the features and comparing similar products, we believe the KME Knife Sharpener System is a great choice for many people. The sharpening system is manual, but it does come with instructions and a guided rod.

If you need a heavy-duty knife sharpener that works with many different types of knives, you will be happy with the KME knife sharpener.

It is more expensive than some of its competitors, but it also has a unique set of features. You get a base for the sharpener and four stones all with different grits.

This knife sharpener isn’t for the faint of heart. If you don’t need or want a serious knife sharpener, you might get overwhelmed with it. Manual knife sharpeners aren’t as easy as electric sharpeners, and the different stones can be confusing.

As with any product, there are people who will love it, and people who won’t need it. Overall, we think the KME Knife Sharpener System is a high-quality product with a lot to offer.

You can use it to sharpen almost any knife in your kitchen. Just be sure you use it before you chop up any more onions.
