Work Sharp Precision Adjust Sharpener – Sharpening on a Budget

I recently picked up the Work Sharp Precision Adjust Knife Sharpener and wanted to share my thoughts. I certainly do not consider myself a knife sharpening expert at this point; however, as an avid EDC guy and knife collector, it only makes sense to dive in and take the hobby to the next level. I’ve used the DMT Angler in the past, which works well as a portable guided knife sharpening kit. But I wanted to pick up a system that was a bit more stationary, something I could use at my benchtop.
And, of course, something that won’t break the bank.

There is no shortage of guided knife sharpening systems available, and choosing one can be a little overwhelming. As a beginner knife sharpener, I was looking for a system that was easy to use and that provided repeatable results. So, did I find what I was looking for in this guided sharpening kit? Yes and No.

While the system is super affordable and easy to set up and relatively use, I found some things that could use some improvement right out of the box. None of which makes this a lousy purchase. There are just a few things that you need to know and a few ways you can address them. 

Before I dig into the pros and cons, let’s look at what you get in the box. Each Precision Adjust requires a minor assembly before you are ready to sharpen. In the box, you’ll find the following. 

  • 1 Tri-Brasive® sharpening stone. The stone includes a 320, a 600-grit diamond, and a fine ceramic plate.
  • 1 Magnetic sharpening slide rod.
  • 1 Benchtop sharpening base with anti-slip pads. 
  • 1 Angle adjustable sharpening chassis. Adjustable from between 15° to 30° in 1° increment.
  • 1 Removable V Block Clamp.
  • User manual


Precision Adjust Knife Sharpener Pros and Cons


  • Affordable
  • Readily Available
  • Easy to Set up


  • Too much flexibility in parts
  • Not enough grits options in sharpening stones
  • The base unit is too light


The Cons

Alright, let me address the Cons first. And remember, this is just one man’s opinion here.

So what do I mean when I say there is too much flexibility in the parts? As soon as I set up the sharpener for the first time, I could see a lot of movement and flex in some key components, for example, the V Block Clamp.

The clamp is allowed to rotate 180° and lock in place, so in theory, you can set your angle and turn the clamp to sharpen both sides of your blade. However, since this piece protrudes out from the chassis with little support, the blade and clamp tend to flex downward when only a light amount of pressure is applied. 

As mentioned, the kit comes with one Tri-Brasive® sharpening stone, which includes a 320 grit, a 600 grit diamond stone, and a ceramic plate. For most applications, this should be sufficient to take a dull blade with chips missing to shaving sharp. However, I feel like this is skipping a couple of progressions to go from a re-profiling coarse stone to the finishing stone. 

Finally, the lack of weight in the base unit leaves me wanting to brace the chassis while in use. Probably a minor concern for most, as there is the tendency to place your hand there anyway. 

The Pros

As for the Pros. Right from the get-go, this is one of the market’s most affordable guided sharpening systems. It comes with everything most people need to take a dull blade and make shaving sharp. 

The Precision Adjust Knife Sharpener is available at a wide range of knife shops, outdoor stores, and Amazon. So you don’t have to look too far to find them in stock. 

The sharpener is easy to set up. Within a few minutes, you will have your first blade clamped and the diamond stones doing what they do best. 

Although I mentioned a few cons above, plenty of upgrades are available for the Precision Adjust. Work Sharp has since released an Upgrade Kit which includes the following. 

  • Coarse Tri-Brasive® Rod: 220, 320, 400 grit diamond. 
  • Fine Tri-Brasive® Rod: 600 and 800 grit Diamond.
  • Leather & Ceramic Rod: Leather strop and ceramic rod for serrations. 
  • Stow and Go carrying case. 


And while Work Sharp has not officially addressed the concern regarding excess flex in the clamp, there are plenty of aftermarket parts available on Etsy which specifically deal with this and more.
