This is the only coarse grinding belt (P120) for use in this sharpener. Price-wise, it’s the cheapest belts among all the models.

This durable flexible belt is manufactured by Norton Abrasives. This is the same belt use by professional sharpening services and knife makers. It has unique cool cutting characteristics that will not alter the blade temper. It’s very affordable and reliable, too.

The belt replacement kit (model WSCMB) consists of 3 individual belts. For just a few dollars, you can easily buy it on Amazon.

Dream of using the Combo Knife Sharpener for medium and fine honing?

As we know, the Combo Knife Sharpener comes with only the P120 grit belt. Maybe Work Sharp thinks that this simple sharpening machine does not require honing, one belt does it all.

Aftermarket Belts

Fortunately, there are some Work Sharp aftermarket belts available on the market.

One of the manufacturers is Red Label Abrasives. You may takes advantage of this opportunity to include more grits to test out the results against the original Work Sharp belts.

It’s also available on Amazon and still considered affordable with a pack of ten belts.

The pack consists of:

  • 2 coarse (P80) grit (for very coarse grinding)
  • 2 medium (P320) grit
  • 3 fine (P800) grit belts
  • 3 ultra-fine (P5000) grit belts (for honing the blade)

All Red Label Abrasives belts are manufactured in USA.

The coarse and fine grits are made of premium aluminum oxide and the ultra-fine grit is made of ceramic. It’s a piece of good news for the knife enthusiasts as they will have more belts to play with, thus sharper and smoother edge.

Some folks prefer to cut with ceramic knife. Unfortunately, there is no diamond abrasive belt available for this model, not even from Red Label Abrasives. Nonetheless, it’s still a blessing as there are different grit belts for replacement.

Work Sharp Diamond Belts

For people who also use ceramic knives at home may consider buying the Knife and Tool Sharpener instead of the Combo unit. With just an extra diamond belt you can include it in your ceramic knife sharpening routine. (see below)

Due to the fact that ceramics is about four times stronger than steel, only diamond belt can sharpen ceramic blade.

Work Sharp Knife & Tool Sharpener (WSKTS)

Work Sharp Knife & Tool Sharpener - precision sharpening guides, premium flexible abrasive belts, repeatable and consistent results, Standard PackagingThis powerful and versatile sharpener is the first portable sharpening device by Work Sharp. It generously includes 6 abrasive belts, two each from coarse, medium, and fine grits.

Don’t ever think to use these belts on the Combo sharpener because it does not fit. It has the same width but it is 2 inches longer than the Combo belts. The belts with different grits are represented in different colors.

The belts of ½ x 12 inches come with different grits:

  • 2 extra-coarse belts (green) – P80 grit (for very coarse sharpening)
  • 2 medium coarse belts (red) – P220 grit (for general sharpening)
  • 2 fine belts (grey) – 6000 grit (for honing and polishing)

Different grits are made from different materials. The P80 grit is made of aluminum oxide, ceramic oxide for P220, and silicon carbide for the 6000 grits.

Quality Belts Ensured

Of all the three types, Norton Abrasives manufactures P80 and P220 grit while the belt for 6000 grit is manufactured by Micro-Mesh. Both are reputable suppliers for Darex Inc. (Work Sharp Company) so we’re very confident of the quality.

Work Sharp tools are so popular that also invited some other companies to share the pie.

Work Sharp WS3000 Wood Tool Sharpener

Work Sharp WS3000 Wood Tool SharpenerThe WS3000 is a bench mounted wood tool sharpener use to restore the edges of chisels, lathe tools, plane irons, carving tools, spoke shaves, scrapers, putty knives and more. The WS3000 Wood Tool Sharpener includes an abundant of different solid abrasive discs from coarse to ultra-fine grit.

There are a total of 11 abrasive discs for a complete range of sharpening.

The WS3000 Solid Abrasive Discs include:

  • 2 of P120 (coarse grit for coarse shaping the bevel of chisels/planes, remove nicks)
  • 4 of P400 (medium grit for general sharpening)
  • 4 of P1000 (fine grit for honing the edge)
  • 1 of P3600 (ultra-fine grit for polishing the edge)

The abrasive discs are to be attached to both sides of the tempered glass wheels which come with the tool. That’s equal to 2 different grits for each tempered glass (top and bottom), so you need a total of 2 tempered glass wheels for the whole sharpening process.

Since Work Sharp sharpeners are so popular, Amazon has a lot of stock.

Look for:

The abrasive discs cannot be used for other sharpeners due to different design but if you have the Belt Sharpening System Attachment for knives (optional) for the WS3000, you can actually use the belts (1” x 18”) from the Ken Onion Edition Blade Grinder except for the ½” wide (6000 grit) belt.

Let’s proceed to the last part of this session – the Automatic Knife Sharpener.

Work Sharp Culinary E5

Work Sharp Culinary E5 Kitchen Knife Sharpener with Ceramic Honing RodOne of a kind, the Culinary E5 is a pre-programmed knife sharpener with a fully automatic function to restore knives at 17° angle. For this angle, you’ll only need the Red P120 Medium belt. This is the belt that is pre-installed at factory before delivery.

The P120 Belt

Simple enough, it seems there is not much choice to play around using different grits. That means one belt does it all.

According to the manufacturer, the machine will vary the speed and duration of use from coarse to medium sharpening and to fine polishing. It plays with speed and duration to achieve the desire results with only one belt.

Strange but it’s true, this model has received very good reviews from the consumers although it depends on one medium belt for the whole sharpening process.

The Medium belt P120 (¾” x 12”) is the same belt use for Ken Onion Edition, and manufactured by the same company, Norton Abrasives. If that’s the case, we believe this belt can also be used for other sharpeners if it fits well.

To buy the Medium belt P120 on Amazon, look for:

Work Sharp Culinary CPAC006 Kit Replacement Sharpening Belts, Red

This replacement belt kit contains 3 of P120 belts. This should be able to last a long time.

Upgrade Kit

This machine is not limited to 17° only. The Culinary E5 has an upgrade kit which can sharpen 15° and 20° of angles. The East and West Guides upgrade kit also comes with various belts to sharpen knives at different angle, including the P120.

  • One of P120ZA Blue Belt- Coarse
  • Two of P120- Red Belt- Medium
  • One of X35- Grey Belt- Fine
  • One of X4- White Belt- Extra-Fine

Of all these belts, the Blue P120ZA belt is to be used only with the 20° West sharpening guides. Do not mistaken the P120 is the same as P120ZA. Any misuse with the wrong guides will cause striations on the face of the blade.

If you’ve worn out the belts, get the Master Replacement Belt Kit below:

Work Sharp Culinary CPAC005 Master Kit Replacement Sharpening Belts, Blue

It includes every belt that comes with the upgrade kit.


To maintain the efficiency of the sharpener for the long haul, getting the replacement belt kit at hand is a must. Different sharpeners come with different belts and it looks very similar. So, make sure you buy the exact belts to reduce the risk of damaging the sharpener.

But some models can share the same belts with other sharpeners. This will never happen unless you have both sharpeners that also use the same type.

We’ve summarized the different types of belts use for all the Work Sharp belt sharpeners. We hope you enjoy this post and have gained a better understanding of the different types of belts for different applications.

Good luck to all Work Sharp fans!
