Has Work Sharp improved on its legendary tool?

The Work Sharp Ken Onion Elite has been the standard for powered abrasive belt sharpening for about a decade. And it’s more than earned its place in knife enthusiasts’ sharpening stations. Yet, Onion and Work Sharp were just getting warmed up.

Unveiled at the beginning of 2024, the Ken Onion Elite Mk2 (KOE Mk2) aims to outdo the original in about every way. But does it?

That’s what I aimed to find out when I pulled out a bevy of knives and put the unit through its paces. Is the sharpener more user-friendly? Does it offer more functionality? Can it unseat the legendary Work Sharp Ken Onion Elite?

Let’s find out.

Work Sharp Ken Onion Elite Mk2 Grinding Attachment

Work Sharp didn’t veer away from the basic functionality of the Work Sharp Ken Onion Elite in the Mk2. For example, blade grinding attachment still uses the same 1”x18” belts as the original and pretty much functions the same.

Onion and the company, however, have enhanced the operation of the attachment in several ways.

The angle adjustments on the grinding attachment now can be made on the fly and without de-tensioning the belt or even turning the unit off. This is done through a round nob under the plate controls, which raises and lowers the idler wheel. A built-in angle indicator allows you to dial in the exact edge.

The aforementioned idler wheel is also new to the system and can be set for three edge types: conventional V, low-angle convex, and high-angle convex. A major plus, this is achieved without tools or even de-tensioning the belt—though, the power must be off.

Work sharp has included a belt guard on the new model, gone are the days of the original’s open face. The guard has a port hole that you can place the hub fastener into (so you won’t lose it!) whenever you convert this unit to the standard three-pulley cassette.

Finally, the Mk2 has an adjustable height reference plate on the platen end of the grinding attachment. Quite simply, this allows for finer adjustments at the platen end.

Overall the build, of the new BGA is more substantial than the original, as there is now more weight to it.

If you prefer to use the standard three-pulley cassette instead of the Blade Grinding Attachment, you can physically swap out the two easily. The power head attaches to either using a simple twist lock connection at the motor housing at the drive shaft.

A nice aspect of the cassette is it includes a scissor guide in addition to a knife guide, which is set at a 65-degree angle. For knives, you use the pull-through method, resting the blade on one of the leather-lined blade rests and pulling the blade through along the belt.

Selecting your edge angle is as easy as turning a dial, similar to the blade grinding attachment. Rotate the knob to the desired edge angle and both blade rests will move in or out simultaneously.

There’s also an included blade rest with plastic rollers that allow you to steady the blade as you pull it through. If you wish to not use these, they simply rotate out of the way and lock into the stowed position.

However, with the cassette, there is no option to adjust for different edge types (standard V, low convex, or high convex). You just get a regular convex edge only, but still razor sharp.

Work Sharp Ken Onion Elite Mk2 Power Head

As for the power head end of things, there are several improvements here. You’ll notice the larger motor housing and inside is a more powerful motor with electronic torque management. The motor senses the load placed on the belt and compensates for it, making this sharpener almost impossible to bog down in use.

The pushbutton speed control with LED light scale shows you at a glance how fast the belt is running. And slowing down or speeding up the belt is as easy as pushing a button.

The Mk2 has a constant on setting—you just squeeze the power trigger and press a button to lock in the setting. Shutting it off is a matter of hitting the stop button or squeezing the power trigger.

The body of the Mk2 has a cast metal overlay that adds rigidity as well as boosts the rough and tumble looks of the tool. Furthermore, the metal overlay makes the unit quieter and dampens vibrations.

Putting the Ken Onion Elite Mk2 to use is a pleasure. However, I’d say, that to step up to a tool of this nature you need to know your manual sharpening skills inside and out—especially when using the grinding attachment. If you don’t know what you’re doing you risk damaging blades or simply spinning your wheels with a sub-par sharpening. Given the guides, the cassette is more forgiving.

I have ten solid years of experience with the original Ken Onion Elite and know the limits of the machine. With this being said, the functionality of the Mk2 is identical to the original and the improvements mentioned make it more user-friendly, improving the overall experience.

I also found the Mk2 is easier to set up and dial in, as well as change angles instantly with the machine powered on. The ability to dial in the edge type (standard V, low convex, and high convex) allows you to tailor the edge format to your specific task for the knife.

Personally, I prefer the high convex, which allows you to cut the edge angle back 2-3 degrees more for enhanced edge sharpness. At the same time, it still retains enough “meat” in the center for lateral strength.

Final Cut

As it goes, the Work Sharp Ken Onion Elite Mk2 doesn’t come cheap with an MSRP of $300. It’s a bit steep for a sharpener. But when you look at what you get, it’s easy to see why it’s still valuable.

While this was primarily designed as a sharpening machine, it’s also a miniature variable speed belt sander that will work on metal, PVC, plastic, and wood. In turn, you receive two machines in one, plus it can handle knives and scissors as well as assist you with projects in your garage or shop. How can you beat that?

Honestly, if you want to take your sharpening game to the next level and beyond, invest in the Ken Onion Elite Mk2 from Work Sharp.
