The honing of knives is done by passing it through the ceramic honing rod. Moreover, the built-in honing rod will also help to sharpen any serrations with ease.

The simple and easy two-step process will get all the knives sharpened in no time. You get a power sharpener and the manual honing ceramic rod with this combo knife sharpener.

The combo knife sharpener features a 120v single speed small motor and uses a 3M abrasive belt (1/2″ x 10″).

Work Sharp Knife Sharpener Buyer’s Guide

Before you move ahead and buy the best electric knife sharpener, it is important you know all the important factors to make a wise buying decision. This buyer’s guide below combined all the crucial points from the manufacturer’s recommendations and various review sites into a practical accessible list below.

Abrasive Materials

Whether it is just a simple touch-up job or you want a comprehensive re-sharpening of the blades, it is necessary that you check the abrasive material used.  The aluminum oxide (P80), ceramic oxide (P220) and the silicon carbide (6000) are the most commonly used abrasive materials in Work Sharp knife sharpeners.

Depending on the model, there are other different types other than the common ones listed above. Know the types of belts your sharpener uses. And always buy the original belts made by Work Sharp to ensure compatibility and quality.

Before you begin to sharpen the knife, use only the right type of abrasive belt for the sharpening job. Abrasiveness is measured in terms of grit. The smaller the number, the more material it will remove.

It is necessary to have both coarse abrasive and fine abrasive material for sharpening knives. While one is used for dull and damaged knives, the other one is used just for polishing and touch-ups.

For example, a belt with grit 80 is used for coarse sharpening and grit 6000 is for polishing and touch-ups.

Never use the fine abrasive belt for coarse sharpening and vice versa. And mixing the two can often lead to damaging the knife permanently.

The Angle Guides

No matter how experienced you are in sharpening the kitchen knives, you will always need the support of the angle guide for precision sharpening of the edges. Most electric knife sharpeners are designed with that in mind to make your life easier. The Chef’s Choice Knife Sharpener does that well with very good reviews. With a little practice, almost anyone can master the sharpening skills and get a well-sharpened knife in no time with the help of the electric knife sharpener.

For a complete range of sharpening angle, try to get a model with varied angle guides to get the job done quickly and with precision. The Work Sharp Ken Onion Edition is a good choice.

When comes to angle guides, you need to ensure that the knife sharpener is capable to deliver the required edges that you need. If you are looking to sharpen or refresh the standard US or European knives, then ensure to invest in a model with angle guides of 20 degrees or more. It is also preferable to have angle guides down to 15 degrees just in case you have Asian knives.

It is important to use the correct angle guide. This will ensure the sharpness of the blade remains consistent. Unless you want to re-profile the knife and change the angle for other purposes or just as an experiment.

Budget vs Versatility

The Work Sharp electric belt knife sharpeners are already very capable of simple touch-ups, polishing, and comprehensive re-sharpening. There are a variety of models to choose from, with prices ranging from under $100 to over $200. Know what you need it for.

Depending on your usage, for a budget of under $100, the Work Sharp tool & knife sharpener and the combo set are a good bet to get all knives sharpened.

Unless you are a heavy-duty user who wants to sharpen a wide variety of different edges and blades, then invest in the Ken Onion edition, preferably with the optional blade grinder attachment. You’ll not regret. A lot of users already recommended this unit. Feel free to read the reviews on Amazon.

Motor Speed

Do you need variable speed so you can fully control the operation? The only model with variable speed control is also the Ken Onion edition. Yes, we highly recommend it. There are many pros and almost zero cons. The design is very versatile with flexibility in mind.

Be careful when operating the motorized sharpener. Make sure you can handle the speed of the motor in case it has been set to run at full speed. Always check the speed control knob first before you start to sharpen. A simple check can prevent unnecessary damaging effects and shocks.


Most of the models come with standard one year warranty with exception of the Work Sharp Culinary E5 Sharpener. The 3-year warranty reflects its reliability and confidence. So check the warranty period before any purchase. Do not assume all models come with 3-year warranty.

The Operation Mode – Precautions and Safety Aspect

For a first timer, always read the manual first and make sure you fully understand the operations and safety instructions. There are warnings that users must understand to avoid injuries and tips from manufacturers to get the best results.

Many users have encountered problems and not able to optimize the sharpening process.

In the case of using the handheld electric belt sharpener, many users have experienced rounding the tip of the knives and doubt its effectiveness.

Was there a flaw in the design? Nope. It was the way how they handle the knife when swiping through the belt.

Firstly, do not apply pressure to the knife; just use the weight of the knife to rest on the belt during sharpening. To avoid rounding the tip, disengage the motor when the tip of the knife touches the belt. All these are written in the user’s manual.

Advantages and Disadvantages

Today, the electric knife sharpeners are designed with advanced technology features which have both advantages and disadvantages.

These high-end sharpeners have better features and are more versatile which can lessen the burden of sharpening knives and virtually any tool that comes with cutting edges. What needs you to sharpen in hours can be accomplished in a matter of minutes.

Of course, it has its disadvantages. Without proper knowledge of handling the electric sharpeners, it may prone to injuries. One of the drawbacks is also the heat generated from high-speed grinding that could soften the steel blade. It is advisable to rest longer between each swipe to cool the blade.

By following the guides in the manual, all knives and tools can be fully sharpened with Work Sharp sharpeners.
