Work Sharp Knife Sharpener Review

Cooking can be an enjoyable and rewarding pastime, but one of the essential needs of any cook or chef is a sharp knife. Keeping your knife sharpened not only makes cutting food easier; it also makes it safer.

One of the leading reasons for injuries in kitchens is from an improperly sharpened or dull knife. They can make it difficult to cut through vegetables or meat, resulting in injury to your hand or fingers.

One of the most reliable and easy-to-use knife sharpeners is the Work Sharp Knife Sharpener. We will look at reviews, how it works compared to other knife sharpeners and why it is worth your money.

What Is the Work Sharp Knife Sharpener?

The Work Sharp Knife Sharpener is an abrasive belt sharpener that not only sharpens knives but can sharpen your tools as well.

The Work Sharp knife sharpener has flexible abrasive belts and sharpening guides so that you can maintain the sharpest blades quickly and easily.

The guides are perfect to use for kitchen knives, hunting knives, pocket knives, filet knives, as well as scissors and serrated knives.

The sharpener can be used for other tools such as garden pruners, lawn mower blades, shovels and much more.

The Work Sharp Knife Sharpener Specs

The Work Sharp knife sharpener can sharpen every knife in your kitchen, as well as outdoor knives and gardening tools, with the abrasive belt system.

The medium and a fine belts allow you to sharpen many types of blades and knives. The course belt can be used to sharpen cutting tools or even shovels and lawn mower blades.

The medium abrasive belt is a multi purpose belt used for all general knife sharpening. The fine belt is used for sharpening serrated knives, quick touch-ups on recently sharpened blades, and to hone knives to that perfect edge.

For easy use the Work Sharp knife sharpener has precision sharpening guides to create consistently sharpened knives and tools.

The guides are interchangeable and include a 40 degree, 50 degree and a 65 degree guides. Use the 40 degree guide for kitchen knives.

For hunting knives and outdoor knives the 50 degree guide should be used. The 65 degree guide should be used for sharpening scissors and serrated knives.

Not only does the Work Sharp knife sharpener sharpen knives but is equipped to sharpen scissors, mower blades, garden shears, shovels, axes and hatchets and any tool with a cutting edge. Simply use the course belt for tools when sharpening.

As tools are much more thick than other types of bladed edges, this will use up more of the abrasion belt, requiring it to be replaced more frequently.

Work Sharp products are American made and engineered by a 4th generation family owned company in Oregon. They stand by their name and will replace the sharpener for up to one year of use.


The Work Sharp Knife Sharpener can be purchased for around $65 online. Considering all of jobs it can perform, it pays for itself relatively quickly.

Where to Buy

There are automatic positioning guides to help you hold the blade exactly where it needs to be for a perfect sharpened edge every time.

The built-in stop feature prevents the blade from becoming too worn down and stops the sharpener if there is too much downward pressure.

Ease of Use

Although the Chef’s Choice electric knife sharpener had many good reviews, it also was a little more labor intensive to sharpen your knives than others on this list. Just to sharpen, not to convert, the edge of your knife it says to swipe 20 times on each side of the knife for stage

1. Swipe 15 times on each side of the knife for stage 2, and swipe 5 times on each side of the knife for stage 3. The sharpener does come with a manual to go over the converting process.

Design Quality

Most people found the quality of design more heavy-duty than other knife sharpeners and as you are swiping the knife, and the guides will ensure that you are getting a nice sharp edge.

  • Flexible spring guides for accurate sharpening angle
  • 3-Stage EdgeSelect
  • 100% diamonds and auto stopping
  • For sharpening both straight edge and serrated blades
  • Over 1000 positive reviews


  • Expensive compared to other knife sharpeners
  • Some reviewers felt it removed too much metal from the blade
  • Leaves the blade scratched on the sides
  • Larger knives did not get as sharp
  • Did not work as well on serrated knives as advertised


All of the knife sharpeners in this review have been tested and reviewed online and exceeded most expectations with high 5 star marks. There were good things and bad things about each and every electric knife sharpener.

However, the stand out because of its versatility is the Work Sharp Electric Knife Sharpener. Not only did it have thousands of positive reviews, it was not the most expensive machine and it simply did more for the cost.

It is made in the USA by a company that has four generations of tool and knife sharpening machines to back it.

We award the Work Sharp knife sharpener five stars and feel it is the best value for the money compared to the other knife sharpeners in this list.

The only downside we felt was that, even though their are guides to help you, you have to make sure that the knife is sharpened correctly.

There is no automatic stop if you apply too much pressure, and you could damage the knife if you do not read the directions and follow them.

There is a slight learning curve, but if you want the benefits of being able to not only sharpen your kitchen knives but outdoor knives and scissors as well, we felt this was an excellent product.
