As someone who’s spent more nights under the stars than I can count, I know the value of a sharp blade. Whether I’m skinning a buck, filleting a trout, or chopping kindling for the fire, a dull edge is a liability. That’s why I’ve put this sharpeneer through its paces in this Work Sharp Ken Onion Elite MK.2 Sharpener review. This isn’t just a sharpening tool—it’s a rugged, reliable companion for anyone who lives by their steel. Let’s break it down and see why this machine deserves a spot in your kit.
Overview and Features
The Work Sharp Ken Onion Edition Elite MK.2 – WSKTS-KO2 isn’t your average sharpener—it’s a dual-threat system built to handle anything you throw at it, from a pocket knife to a camp axe. This rig combines two powerhouse components: the Sharpening Cassette and the Blade Grinding Attachment (BGA), each designed with its own strengths to keep your edges in fighting shape. It’s like having a full sharpening shop packed into one unit, and it’s loaded with features that make it a standout for anyone who depends on their blades.
The Sharpening Cassette is the precision half of the duo. It’s got adjustable sharpening angles ranging from 15° to 30°, dialed in with 1° increments so you can nail the exact bevel you need—whether it’s a fine 15° for a fillet knife or a stout 25° for a bushcraft blade. There’s even a dedicated 65° guide for scissors, which came in handy when I resurrected a pair of shears that hadn’t cut right since last season. The guides are lined with leather, a smart touch that cradles your blade and keeps it free of scratches or burrs. It’s powered by a pull-through system that’s dead simple: set your angle, pull steady, and let the abrasive belts do the work. The belts themselves are narrow—perfect for controlled, repeatable passes—and the whole setup runs off a variable-speed motor that you can tweak from a gentle 1200 SFM for touch-ups to a beefy 2800 SFM for heavier sharpening jobs.
Then there’s the blade grinding attachment, the heavy hitter of the pair. This thing’s a beast, rocking 1” x 18” belts that give you room to maneuver on bigger blades—think machetes, hatchets, or that oversized camp knife you’ve been meaning to rehab. The angle range opens up even wider here, from 10° to 35°, letting you customize edges for anything from razor-thin slicers to tough-as-nails choppers. It’s got three convex edge profiles built into the design, which is a game-changer for outdoor blades—convex grinds hold up better under abuse, and I’ve put mine through hell splitting wood and still kept the edge. The BGA comes with a full belt kit: P120 Extra Coarse for major repairs, X65 Coarse for shaping, X22 Medium for refining, X4 Fine for honing, and 6000 Extra Fine for a polished finish that’ll cut paper like butter. You swap belts quick with a tension-release lever, and the motor’s seven-speed control—complete with an LED display—lets you match the grit to the task without overheating your steel.
The whole system’s tied together by that motor, a workhorse that adjusts on the fly with a flick of a switch. It’s got enough torque to grind through tough jobs but enough finesse to polish without burning an edge. The Elite MK.2 also includes little extras that add up: a quick-release mechanism to flip between Cassette and BGA, a sturdy platform that keeps everything stable, and a design that’s intuitive even if you’ve never touched a belt sharpener before. It’s a kit built for versatility—whether you’re maintaining a daily carry, fixing a chipped blade, or putting a custom grind on a prized piece of steel, this thing’s got you covered.
Build and Durability
Out in the field, gear takes a beating, so I’m picky about construction—and the MK.2 Elite doesn’t disappoint. This thing’s built like a tank, engineered in Ashland, Oregon, at Work Sharp’s solar-powered facility. Every piece feels purpose-made, from the solid base that anchors it during heavy grinding to the motor that hums with power, no matter how hard you push it. That variable-speed motor—running from 1200 to 2800 SFM across seven settings—has the grunt to tackle anything I throw at it, and the LED display keeps me dialed in without squinting at tiny markings. I’ve used it in dusty sheds and damp cabins, and it’s shrugged off the grit and grime like it’s nothing.
The design’s smart, too. Switching between the Sharpening Cassette and the Blade Grinding Attachment is tool-free and fast—just a quick release and you’re set. No fumbling with screws or losing parts in the dirt. The BGA’s angle dial is a standout: smooth, precise, and locks in tight, even when I’m grinding a stubborn hatchet blade back to life. The whole unit’s got some weight to it—about 12 pounds—so it stays put on the workbench, no matter how much pressure I lean into it. That heft’s a plus when you’re working on big steel, but it’s still compact enough to tuck into a corner of the shop or haul to a hunting camp without breaking your back.
Durability’s where it really shines. The housing’s tough as nails—feels like it could take a drop off the tailgate and keep on ticking. The belts on the BGA hold up under serious abuse; I’ve chewed through chipped edges and still had life left in the P120 grit. The leather-lined guides on the Cassette? They’ve kept my blades scratch-free through dozens of passes, no wear in sight. I’ve run this thing for hours—sharpening everything from pocket knives to machetes—and the motor doesn’t overheat or bog down. It’s not some flimsy gadget that’ll quit after a season; this is a workhorse built to last years, maybe decades, if you treat it right. Out where reliability’s not optional, that’s the kind of build I trust.
Performance in Action
Let’s talk results. The Sharpening Cassette is a godsend for quick tune-ups. I’ve run my field knives through it—skinners, folders, even a beat-up kitchen blade from camp—and it delivers a clean, consistent edge in minutes. Set your angle, pull steady, and you’re back to slicing with surgical precision. The variable speed is clutch—low for finesse, high for chewing through dull steel. I’ve even sharpened my wife’s garden shears with the 65° guide, and they cut like new.

The blade grinding attachment, though? That’s where this sharpener earns its stripes. I’ve used it to reshape a chipped hatchet blade after a rough season, and it chewed through the damage like it was nothing. The wider belts and broader angle range let you tackle big jobs—think machetes or heavy bushcraft knives. The convex edge options are a dream for outdoor blades; I put a convex grind on my go-to camp knife, and it’s held up through weeks of chopping and batoning. From coarse grit to a 6000-grit polish, the belt progression is smooth and logical—perfect for getting an edge that’s both durable and razor-sharp.

Pros and Cons
Here’s the straight dope. The MK.2 Elite is fast, adaptable, and built to last—ideal for someone like me who needs a blade ready at a moment’s notice. The dual-system approach means it’s got you covered whether you’re maintaining a daily carry or rebuilding a wrecked edge. The leather guides and precise angle control are thoughtful touches that save your steel from scratches and guesswork.
On the flip side, it’s not cheap—this is an investment, not a budget buy. The learning curve isn’t steep, but it takes a few runs to master the BGA’s belt tension and angle tweaks, especially if you’re new to belt sharpening. And while it’s portable enough for a shop or cabin, it’s not something you’d haul into the backcountry. This is a basecamp tool, not a trail kit.

Final Verdict
The Work Sharp Ken Onion Edition Elite MK.2 – WSKTS-KO2 is a top-tier sharpener for anyone who lives and works outdoors. It’s got the muscle to handle heavy-duty blades, the finesse to polish a fillet knife, and the durability to keep up with a hard-use lifestyle. I’ve trusted my edges to it—from hunting season to camp chores—and it’s never let me down. If you’re serious about your tools and want a sharpener that can keep pace with your adventures, this is the one. It’s not just gear; it’s a partner you can rely on when the wild calls.
