What could be better
- −Slower and more hands-on than electric sharpeners

Best for: Home cooks who want razor-sharp edges without learning freehand whetstone technique
Visit Work Sharp →This Work Sharp knife sharpener review focuses on the Precision Adjust, the family-owned Oregon company's most popular guided sharpener. Work Sharp makes everything from pull-through and electric kitchen sharpeners to belt grinders such as the Ken Onion Edition. The Precision Adjust sits in the middle: a manual system that clamps your knife and holds the sharpening angle for you, so you get whetstone-like results without years of practice.
It is a close cousin of the Precision Adjust Elite, which adds more grits, a leather strop and a case, and the Professional Precision Adjust, a higher-end model. Based on Work Sharp's specifications, independent tests from Bon Appétit and Outdoor Life, and owner reports, here is how the standard model performs for kitchen knives.
Design and setup
The Precision Adjust consists of a benchtop base, an angle-adjustable chassis, a V-Block clamp that grips the blade, and a slide rod that carries the abrasive handle. You clamp the knife, set the angle on the dial, then sweep the abrasive along the edge in smooth strokes, flipping the clamp to do the other side.
The kit weighs about 0.8 kg and sits steadily on a counter. The downside is that it comes in several parts, and Bon Appétit's testers found the need to take it apart for storage a chore.
Key features: why a fixed angle helps
Holding a consistent angle is the hardest part of sharpening by hand. The Precision Adjust removes that problem: once set, the angle stays the same on every stroke. You can choose anything from 15° to 30° in 1° steps, which covers thin Japanese-style blades as well as tougher Western kitchen and outdoor knives.
The Tri-Brasive handle rotates between three surfaces: 320 grit diamond for shaping a dull edge, 600 grit diamond for sharpening, and fine ceramic for refining. Work Sharp estimates the abrasives last around 200 to 300 sharpenings before replacement.
- 15–30° angle guide in 1° steps
- Coarse and fine diamond plates
- Fine ceramic for finishing
- V-Block clamp for a range of blade sizes
- Replacement abrasives available
Performance: how sharp does it get?
Independent testers agree that results are excellent. Bon Appétit said the Precision Adjust produced some of the sharpest edges in its test, describing it as a mechanically assisted whetstone. Outdoor Life named the Precision Adjust Elite its best sharpener under a mid-range budget, praising its precise, repeatable edges on everything from pocket knives to kitchen knives.
The trade-offs are time and technique. Expect a short learning curve and a few minutes per knife, more for very dull blades. Some testers wished the clamp held knives more firmly, and long chef's knives need more strokes because the abrasive plates are narrow.
Precision Adjust vs Elite, electric and whetstones
The Precision Adjust Elite adds more diamond grits, a ceramic plate, a ceramic rod for serrations, a leather strop and a carry case, making it the better choice if you want polished edges or sharpen serrated knives. Work Sharp's electric kitchen sharpeners are much faster and simpler but offer a fixed angle and less control. Whetstones cost less and give the most flexibility but take real practice to use well.
Who should buy the Work Sharp Precision Adjust?
It is a great fit for home cooks who care about sharp knives, own a mix of Western and Japanese blades, or want to learn proper sharpening without freehand risk. It is less suitable for anyone who wants a 30-second touch-up; a honing rod or an electric sharpener is better for that. Pair it with regular honing to keep edges sharp between sessions.
How to use the Work Sharp Precision Adjust
Start by marking the edge with a permanent marker so you can see where the abrasive is removing metal. Clamp the knife in the V-Block with the edge facing up and set the angle to match the existing bevel. Use the 320 grit diamond side with light, even strokes from heel to tip until you feel a small burr along the opposite side.
Flip the clamp and repeat on the other side, then move to the 600 grit diamond and finally the fine ceramic, using fewer and lighter strokes at each stage. Test the edge carefully on paper or a tomato. Clean the abrasives with water and a soft brush after use, and keep the parts together in a drawer or box so nothing goes missing.

Frequently asked questions
Is the Work Sharp Precision Adjust worth it?
+
For people who want very sharp kitchen knives at a modest cost, yes. Independent testers rate its edges among the best, but it is slower to use than an electric sharpener.
What angle should I use for kitchen knives on the Work Sharp Precision Adjust?
+
Many Western kitchen knives are sharpened at around 20° per side, and many Japanese knives at around 15°. Check your knife maker's advice and match the existing edge where possible.
Can the Work Sharp Precision Adjust sharpen serrated knives?
+
The standard kit is designed for plain edges. The Precision Adjust Elite includes a ceramic rod for serrations, and Work Sharp's electric kitchen sharpeners also handle serrated blades.
What is the difference between Work Sharp Precision Adjust and Elite?
+
The Elite adds more abrasive grits, a leather strop, a serration rod and a carry case. The standard model has three abrasives on a single rotating handle.
How long do Work Sharp Precision Adjust abrasives last?
+
Work Sharp estimates about 200 to 300 sharpenings, depending on how dull the knives are and how hard you press. Replacement abrasives are available.
Does Work Sharp make an electric kitchen knife sharpener?
+
Yes. Work Sharp sells electric kitchen sharpeners, including a professional model with belt abrasives, a 17° guide and one-touch shape, sharpen and refine programs.
Is a guided sharpener better than a whetstone?
+
A guided sharpener such as the Precision Adjust makes it much easier to hold a consistent angle, so beginners usually get sharper, more even edges sooner. A whetstone is cheaper and more flexible once you have the skill, but it takes practice to avoid rounding the edge. Many home cooks start with a guided system and add a stone later.
The Work Sharp Precision Adjust shows that a guided system can deliver outstanding edges without a big budget. Its locked angle, simple abrasives and solid results make it one of the best manual sharpeners for home cooks, as long as you accept a few extra minutes and some assembly. If you want polished or serrated edges, step up to the Elite kit.
