The new 3-step Senzu knife sharpener is an upgrade of the rigorous 2-stage Senzu sharpener. It is the first Senzu sharpener that can sharpen your blades with a 3-stage diamond-coated wheel system. This tool claims to sharpen your blade within 5 seconds.

Most chefs love and have used Senzu sharpeners for years, but this model is a game-changer. This is the first diamond-coated wheel version by Senzu with 3 sharpening slots. And the addition of the diamond slot to this model is a significant upgrade. The 2-stage Senzu sharpener only featured the coarse and ceramic slots.

Although it’s not ideal, this sharpener can also handle tactical, German, Japanese, hunting, and utility blades. Senzu knife sharpener is possibly the best option for both ceramic and metal blades.

Features and Benefits


Senzu sharpener comes with a well-crafted handle that is made from ABS plastic. ABS plastic is one of the most durable materials that are used for mechanical purposes.

ABS is the best material for building kitchen wares since it can withstand high temperatures of up to 200 degrees Fahrenheit. Therefore, you don’t have to worry about your sharpener’s handle melting in your hot kitchen. This material can be heated to its melting point several times and then cooled without any major degradation.

This durable and robust tool is designed to serve you for a very long time. This tool comes with a perfect grip that requires a soft grip and touch. And the good news is that both left and right-handed chefs can use it.

The handle features a non-slip cushion, which keeps your tool steady as you sharpen your blades. The non-slip cushion is a safety feature that helps keep you and everyone in your kitchen safe.

3-Stage Sharpening Head

Senzu knife sharpener comes with a unique 3-stage sharpening system that can handle any blade. In fact, each slot is meant to handle a certain type of blade or function.

One of the main reasons why chefs love this tool is that it comes with a feature for just polishing an already sharp knife. These slots include:

Ceramic Slot

The ceramic slot is made from premium diamond abrasive. Diamond is one of the strongest materials on the planet; therefore, this slot can handle any blade.

The ceramic slot is used to repair some of the most damaged tough blades that haven’t been used for years. The diamond abrasive can restore damaged and blunt blades into the original form.

Coarse Slot

If the edge of your blunt blade has lost its V-shape, then the Senzu sharpener is the best tool for you. The coarse slot can restore the V-shape.

This tool can cut through your blade’s material and restore the edge angle. This slot is great for the daily maintenance of your knife, and it can handle medium blunt blades.

Slot Fine

This slot is perfect for polishing already sharp blades. It is an ideal option for chefs who want to add quick touch-ups to their blades before they start preparing their ingredients. The third slot leaves your knives clean and ready for cutting and slicing. It fine-tunes your blade for a clean polish.

Things To Consider Before Purchasing A Knife Sharpener

Everybody who owns a knife will eventually have to sharpen it. You can use a sharpening stone, pay for knife-sharpening services and an electric or manual pull-through sharpener.

As a professional chef or a person who cooks for their family, you already know how hard it is to work with dull blades. Cutting and slicing your ingredients with a dull blade can be tedious, especially since you will have to apply more pressure on the knife.

Working with a blunt blade is more dangerous than the sharp ones. And it is the main reason why thousands of knife enthusiasts end up in emergency rooms every year.

Senzu sharpeners can handle all of the knives in a kitchen — with the exception of serrated blades — and is a great addition for the chef who loves keeping their knives sharp.

Plus, the fact that they are easy to use means anyone in the kitchen can sharpen the blades. So, it is an excellent option for every home, and it can never disappoint anyone preparing a meal for their family.

However, being a manual pull-through sharpening tool, this sharpener might not be the best for some EDC and hunting blades. Most of the camping, hunting, tactical and EDC blades are made from sturdy materials.

These blades vary in size and shape; therefore, sharpening some of them with this sharpener can be tricky.

Also, some of the EDC knives have partially serrated blades. Serrated blades need a different type of sharpener.

So here are a few other things you must consider before purchasing this product:


Your ideal sharpener should be perfect for the job at hand. It should be able to sharpen the different types of blades in your kitchen.

And for extremely sharp edges, a tough, abrasive material will be required. The sharpening material must be tougher than your blade.


To prevent accidents when sharpening your blades, it’s advisable only to get products that have proven themselves in terms of safety.

And just like most renowned sharpeners, Senzu sharpener is encased, which helps protect your body. A great sharpener should be safe to use.

Materials Used to Make the Sharpener

As mentioned before, if you want an extremely sharp edge, the sharpening material must be tougher than your blade. Fortunately, most modern sharpeners come with more than two sharpening slots.

These slots are for dealing with certain types of blades. Therefore, look for one with more slots for extra sharpening options.


Since you will be dealing with sharp blades that vary in size, design, and style, your safety is essential. So, look for a tool with a perfectly designed handle that can give you a perfect grip. Remember, the sharpening process can be vigorous.


Most household appliances use a lot of energy, and adding an extra electric tool is not a good idea. So you can opt for a manual sharpener or a low energy consuming knife sharpener.

However, the amount of electricity used will depend on the amount of time it takes for all your blades to become sharp.

Electric sharpeners are very easy to use and less tedious. But, if you are not careful, you might end up removing more metal than necessary. Manual knife sharpeners require some skill, but you have a low probability of thinning out the knife too much.

With manual sharpeners, you are more in control than with an electric sharpener. Remember, you are the one setting the sharpening speed of your tool.

Edge Angle

Most chefs have either Asian or western style knives. The Asian knives are meant for dealing with softer vegetables and fish. The edges of the Asian blades have a finer angle (13 to 15 degrees). Western knives have strong, large blades that come with a 20-degree edge.

If you are a serious chef who owns Japanese and German knives, then your search can be complicated. Japanese blades should be sharpened to a 17-degree edge. Therefore, the blade styles of your set of knives play a crucial role when looking for a knife sharpener.

Specialty Sharpening

You might be looking for a sharpener for your kitchen blade, but do you know that there are models that can handle other tools.

Some of these tools include cleavers, scissors, and ceramic knives, among others. These sharpeners can be a bonus for you.
