The Work Sharp Professional Precision Adjust Knife Sharpener Tool is an advanced sharpening system designed for both enthusiasts and professionals who demand precision and ease of use. After using this sharpener extensively, I can confidently say it is one of the best investments I have made for maintaining my knives.

Key Features of the Work Sharp Professional Precision Adjust Knife Sharpener

Professional-Level Sharpening with a Solid Build

One of the standout features of this sharpener is its metal construction, which provides a stable and durable sharpening experience. Unlike plastic-based sharpeners that feel flimsy, this tool is built to last. Whether sharpening kitchen knives, hunting knives, or small pen knives, the solid structure ensures a consistent and precise sharpening process.

Adjustable Sharpening Angles for Versatility

A major advantage of the Work Sharp Professional Precision Adjust Knife Sharpener is its angle adjustment feature. It allows users to adjust the sharpening angle from 15 to 30 degrees, catering to various knife types. This flexibility ensures that each knife gets the appropriate edge for its specific use. The included digital angle indicator makes this adjustment process easy and accurate, removing guesswork and improving sharpening efficiency.

Seven Abrasive Grit Options

The sharpener comes with seven abrasive grits, including 220, 320, 400, 600, and 800 diamond stones, a fine ceramic stone, and a leather strop. These options allow users to customize the sharpening process according to their needs. Coarse grits work well for reshaping dull or damaged blades, while finer grits help achieve a razor-sharp edge. The ceramic stone and leather strop provide the finishing touches for an ultra-smooth, polished edge.

Exceptional Precision and Ease of Use

What sets this sharpener apart is its ability to deliver professional-level results with minimal effort. The adjustable angle guide ensures that each stroke is accurate, preventing uneven sharpening. The sharpening arm moves smoothly, providing consistent contact with the blade. Even for those who are new to sharpening, this system makes it easy to achieve professional-grade sharpness.

After testing this sharpener on various knives, I was genuinely impressed by its performance. Here are some key aspects I particularly liked:
  • Stability and Durability: The metal construction provides a sturdy base, ensuring that the sharpener doesn’t wobble or move during use. This made the sharpening process smoother and safer.

  • Precise Angle Adjustments: Adjusting the sharpening angle was incredibly easy with the built-in digital angle indicator. This feature gave me confidence that each knife was getting the right sharpening angle.

  • Smooth and Effective Sharpening: The different grits allowed me to sharpen a variety of knives effectively. Whether restoring a dull knife or fine-tuning an already sharp blade, the process was seamless.

  • Finishing Touch with the Leather Strop: The inclusion of a leather strop was a great touch. It helped refine the edges of my knives, giving them an ultra-sharp, polished finish.

  • Easy Setup and Use: Unlike complex sharpening systems that require a steep learning curve, this tool was easy to set up and use right out of the box. Even as someone who appreciates precision, I found it very user-friendly.

Why the Work Sharp Professional Precision Adjust Knife Sharpener Stands Out

Superior to Traditional Sharpening Methods

Compared to manual whetstones or fixed-angle sharpening tools, this sharpener offers superior control and precision. The ability to adjust the angle ensures that each knife gets the best possible edge, unlike traditional methods that often rely on estimation.

Comprehensive Knife Maintenance

Many sharpeners on the market focus only on sharpening, but this system goes beyond that by offering grit variety and a leather strop for final polishing. This makes it a complete sharpening solution, catering to both minor touch-ups and extensive blade restorations.

Designed for Longevity

    5.0 out of 5 stars Best sharpener I have used.

    TL,DR: The best sharpener I have used. Easy to set up. Easy to use. Put razor sharp edges on two old knives, right out of the box. Performed fantastic. Only major issue was a little wiggle in the clamp.

    Main review:
    I just got my Precision Adjust Pro, today. Right out of the box, I can say the product seems well made. I like the fact the box contains divided compartments to store everything. While some form of blow molded case would be better, it would increase the price drastically.

    As for performance: My first two knives were 30 year old kitchen knives from a well known cutlery company. One has been used so much I wasn't sure it could be saved. The other was barely used but was never very sharp, even when brand new. I was able to easily put wicked-sharp edges on both knives.

    The system is absolutely easy to use, easy to set up, and performed mostly flawlessly. The digital angle indicator let me dial in the recommended edge for both knives. I am looking forward to years of use. I am not the best at hand sharpening. I can put a decent enough edge on my pocket and hunting knives. I would never have tried kitchen knives by hand. This product made it simple.

    The only negatives I have found so far are:
    1. The V-block clamp didn't hold the most securely. As I worked the stones over the blade, I noticed that one side of the blade tended to wiggle out slightly. I don't know if it was the thin blades and their distal tapers, the clamps grip not being "sticky" enough, or the clamp itself doesn't put even enough pressure across the blade to hold. These were not large knives so only time will tell if this will become a bigger problem with my bigger stuff.

    2. Stone grits. I think what comes in the box is great to start with. I would love to see Work Sharp release a number of higher grit stones beyond 800.

    This is an extremely well designed and constructed sharpening jig. For those who want their knives super sharp and are willing to put some time and effort into sharpening, this is for you! It’s completely manual of course, it only holds the knife and stone. The jaws that hold the blade are very well designed and sturdy but with long blades it’s still necessary to use care and keep the blade perpendicular.
    One of the reasons this jig works so well is that the sharpening stones themselves are very sharp and aggressive diamond stones. They cut quickly and I’ve found that no downward pressure at all is needed on the stone, its weight alone gives the best results. I found that if I use the 220 grit plate to put a completely new angle on a knife, it takes a fair amount of time and work to put a razor edge on it, using each plate in succession. But it’s worth the effort. The sharpening jig maintains the angle through all the grits and the result is excellent. One thing that Work Sharp doesn’t mention is adding a secondary bevel. That is, start with the knife sharpened to say, 15 degrees and then add a very narrow secondary bevel of 20 degrees. It’s a technique used by many woodworkers to produce ultra-sharp chisels and plane irons.

    5.0 out of 5 stars Easy to use, works great on most knives.

    Pros: Can put a wicked edge on a knife. So easy to use that it's fun. Nice solid construction. Doesn't need to be bench mounted.
    Cons: Proprietary sharpening plates. Really only worth the price if you have a lot of knives, or depend on your knives to be keenly sharp. Not recommended for scissors or non-standard edges, like on lawnmower blades or hedge clippers, machetes, etc.

    One thing I've noticed while trying to learn the science of sharpening is that the people who have really invested themselves in the hobby of collecting knives and keeping their edges keen take their stuff seriously. Those who have refined the science into an art seem to swear by a series of whetstones. I've tried my hand at them, but being able to steady the blade at a consistent angle through the grind is a knack which is not easy for my sometimes wobbly hands. And as someone who isn't a knife collector and has one good Wusthof, a Miyabi and a Henckel cleaver for the kitchen, and a pocket knife for the toolbox, I feel reluctant to even offer an opinion on sharpening techniques, with all the good ole boys who are whittling hair off their arms on YouTube. But bear with me, because I like a sharp knife and a well-designed product, which this is.
    My first experience with Work Sharp was with one of their belt sharpening systems, and I am still pretty impressed with that- it put a nice edge on my knives, and revitalized an old pair of my mother's scissors. I think that's actually a good deal, since you can apply it to garden tools and scissors, which this isn't well suited to. But this sharpening system is meant for knives alone, and it does its job exceptionally. An ample library of video tutorials exist to refine your technique, but one can start right out of the box after a one-page quick start guide. I began with a cheap stamped metal cleaver which had been hiding in the back of a drawer to get the hang of it, and despite my aforementioned dexterity issues, got some pretty satisfactory results. I loaded the Wusthof kitchen knife next, (a much harder steel,) set the angle at 25 and worked the blade until I could feel a burr, then flipped it to the opposite side, (a process made easy by the rotating clamp,) and repeated, working my way down the sharpening stones until I was down to the strop, with a bit of polishing compound. I then inspected the knife and out of habit got a wadded up towel to clean the dust off the blade. The edge was so sharp that it slid through the towel before I knew what was happening, and it continued into my thumb. Dear reader, I realize that I have mentioned my lack of dexterity earlier, but I'm not a complete klutz, nor am I an idiot. Nevertheless, I was bleeding from my own kitchen knife. From a very neatly formed slice through some of the thickest skin at the tip of my thumb.
    Consider that both a warning and an endorsement. One (heavily bandaged) thumb up!
