Two guided knife sharpening systems on a workbench: a benchtop clamp-and-arm sharpener and a handheld clamp with guide rods

Work Sharp vs Lansky: which guided sharpener should you buy?

Both clamp the knife so you don't have to hold the angle. The Work Sharp Precision Adjust is easier and adjusts in one-degree steps; a Lansky kit is cheaper, more portable and gives you more grits. Here's how to pick between them.

How we pick Updated · We earn a commission when you buy through our Amazon links.

Buy the Work Sharp Precision Adjust if you want the easiest guided sharpener with any angle from 15° to 30°; buy a Lansky kit if you want more grits for less money and a system small enough to take camping. Both clamp the blade so the angle stays consistent. The Work Sharp is faster to set up and needs no oil; the Lansky asks for a bit more technique but rewards it with a wider grit range.

The key difference: what moves

How the Work Sharp Precision Adjust and Lansky systems hold the angle Left: the Work Sharp holds the knife in a clamp on a benchtop base and the abrasive slides on a rod whose angle is set by a dial. Right: the Lansky clamp holds the knife and a guide rod on each hone passes through a preset angle hole in the clamp; you hold the clamp in one hand.

Work Sharp Precision Adjust: the easier one

Easiest guided system

Work Sharp Precision Adjust

The Precision Adjust sits on a benchtop base, clamps the knife, and lets you dial in any angle from 15° to 30°. A three-sided abrasive on a slide rod sweeps across the edge, and you rotate it from 320 diamond to 600 diamond to fine ceramic as you go. There's no oil, no hand-held clamp to balance and very little to learn.

The trade-offs: three abrasives is a narrower range than Lansky's five, and independent reviewers have measured the angle drifting a few degrees toward the ends of long blades, a common issue with pivoting-arm designs.

  • Angle15° to 30°
  • AbrasivesTri-Brasive 320 & 600 diamond, fine ceramic
  • Powernone
  • Includedbenchtop base, knife clamp, slide rod
  • Warranty3 years

Why it stands out

  • Fastest setup and easiest to use
  • Any angle from 15° to 30°
  • Dry abrasives, no mess

Think twice if

  • You want very coarse grits for reprofiling or a very fine polish
  • You need to pack it into the field

Lansky: more grits for less

Best value guided kit

Lansky Deluxe 5-Stone System

Lansky's system has been around for decades and it's still one of the best-value ways to get a consistent edge. You clamp the blade, push each hone's guide rod into one of four angle holes, and stroke the hone across the edge. The Deluxe kit runs from a 70-grit extra-coarse hone, useful for reprofiling or repairing chips, to a 1000-grit ultra-fine ceramic for finishing.

It takes more coordination than the Work Sharp: you hold the clamp in one hand and the hone in the other (or buy Lansky's optional mount), and the hones use oil. Owners also note some play in the clamp holes, which can make the angle slightly less precise than the numbers suggest.

  • Angles17°, 20°, 25°, 30° preset
  • Honesextra coarse (70), coarse (120), medium (280), fine (600), ultra fine (1000)
  • Materialalumina oxide and ceramic
  • Includedclamp, guide rods, honing oil, case
  • Warranty1 year (listing)

Why it stands out

  • Five grits from extra coarse to ultra fine
  • Compact case for camping and hunting trips
  • 14,000+ ratings

Think twice if

  • You want an adjustable angle between the presets
  • You dislike oily cleanup
  • You find it awkward to hold a clamp and stroke at the same time

Which is better for your knives?

Kitchen knives

Long chef's knives are where the differences show. Both systems clamp the blade near its middle, so the angle changes slightly toward the heel and tip of a long blade. The Work Sharp's base keeps the knife steady and the motion simple, which most home cooks will find easier. The Lansky's lowest preset is 17°, so if your Japanese knife maker recommends around 15° per side, the Work Sharp gets closer. For a whole block of kitchen knives, consider an electric instead; see the best sharpeners for kitchen knives.

Pocket and EDC knives

Both are good here, because short blades sit almost entirely within the clamp's sweet spot. The Lansky's five grits make it easy to reset a factory edge to your own angle, and its case is small enough for a backpack. The Work Sharp is faster for regular touch-ups at a bench. See our pocket knife sharpener picks.

Hunting and outdoor knives

Thicker blades sharpened at 20° to 25° per side suit either system. If you want to sharpen at camp, the Lansky wins on portability. If you'll sharpen at home after the trip, the Work Sharp is quicker.

Learning curve and technique

With the Work Sharp, the main skills are clamping the knife centered and using light, even strokes from heel to tip. With the Lansky, add holding the clamp steady, keeping the guide rod seated in its hole, and applying oil to the hone. Neither takes long to learn compared with a freehand whetstone; both remove the hardest part, which is holding a consistent angle. A marker on the bevel shows you quickly whether you're hitting the whole edge.

Want the easiest possible guided sharpenerWork Sharp Precision Adjust
Need angles like 15°, 18° or 22°Work Sharp (adjustable)
Want to reprofile or fix chips cheaplyLansky Deluxe (70-grit hone)

Want a premium, all-metal systemWork Sharp Professional Precision Adjust

Not sure which angle your knives need? Many Japanese kitchen knives are sharpened around 15° per side, many German knives around 20° and many pocket and hunting knives around 20° to 25°; check your knife maker's recommendation and see our angle chart. Note that 15° is below Lansky's lowest preset (17°).

Other guided systems to consider

The Spyderco Sharpmaker uses fixed 15° and 20° rods and is excellent for maintenance and serrated edges; read our Sharpmaker review. For pocket knives on the go, the Work Sharp Guided Field Sharpener is pocket-sized.

The bottom line

For most people, the Work Sharp Precision Adjust is the better buy: easier, cleaner and adjustable to any angle from 15° to 30°. Choose the Lansky Deluxe 5-stone if you want the widest grit range for the money or a kit you can take into the field. Upgrade to the Precision Adjust Elite if you have serrated knives.

Questions people ask

Is Work Sharp better than Lansky?
For most beginners, the Work Sharp Precision Adjust is easier: it sits on the bench, adjusts from 15 to 30 degrees in one-degree steps and uses diamond and ceramic abrasives with no oil. A Lansky kit is cheaper, more portable and offers more grit stages. Neither is better for everyone.
What angles does a Lansky sharpener use?
Lansky's clamp has preset angle holes at 17, 20, 25 and 30 degrees. You choose a hole and insert the guide rod of each hone into it. That covers most kitchen, pocket and hunting knives, but there's no setting in between.
Can the Work Sharp Precision Adjust sharpen serrated knives?
Work Sharp lists serrated edges among the base model's uses, and the Precision Adjust Elite adds a dedicated conical ceramic rod for serrations. Lansky sells a serrated hone in its Professional kit.
Does the Lansky need oil?
Lansky's alumina oxide and ceramic kits come with honing oil, and Lansky recommends using it on those hones. The diamond kit doesn't need oil. The Work Sharp Precision Adjust's abrasives are used dry.
Which Lansky kit should I buy?
The Deluxe 5-stone kit is the best value for most people: extra coarse (70) through ultra fine (1000), plus honing oil and a case. Choose the Diamond kit if you sharpen very hard steels, and the Professional kit if you need the serrated hone.
Which Work Sharp Precision Adjust should I buy?
The base model covers most home users. The Elite adds separate coarse and fine diamond plates, a serrated rod and a leather strop. The Professional model adds metal construction, a digital angle indicator and seven abrasives from 220 diamond to a leather strop.
