  ABSOLUTELY THE BEST SHARPENER PERIOD

  Absolutely incredible sharpening system, I've own many different options to sharpen knifes from manual water stones to bench grinding wheels and this is by far the best. This thing can take a butter knife to razor sharp in 30 minutes but once you have you knifes sharp you can touch them up in seconds. I owned the original version of this system which had many flaws that this newer version fixes, it sharpens anything from large kitchen knifes to tiny swiss army keychain knifes to a mirror polish you could shave with literally. It's hard to show in the pictures how good it really gets these knife but once I got this system I literally took my day off and sharpened every single blade in my house haha. If you want a one system does it all sharpener then you should absolutely get this!!!

  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.

  An Amazing Tool

  I have bought some knife sharpeners in the past- some electric, grinding stones, and sharpening rods. So far I love this tool in that it enables you to sharpen at a specific angle. The angle calculator is battery powered and you always hit the same angle each time you make a pass. You end up with a sharp knife in a short time. I use this mainly for sharpening my kitchen knives since I do a lot of meal preparation from cutting up veggies to meats of various types. I love the practicality of this tool- it's simple and very effective. The instructions are easy to follow and if unsure you could always check videos from YouTube. This is a tool you're gonna have for a long time. It's well designed and the materials are well built with quality. It comes with angle recommendations depending on the type of knife you're trying to sharpen. I have sharpened my kitchen knives from short to long ones. I have also sharpened my clever that I use for chopping and cutting veggies.

  This Is The Pro Sharpener You Want.

  I'm a big EDC guy, especially when it comes to collecting premium fixed blade and folding pocket knives. But I'm not an expert knife sharpener. Not even close. I've never sharpened using anything other than an Orange Ninja three stage pull through sharpener. The WorkSharp Professional Precision Adjust kept getting high praise from all the knife guys I regularly watch on Youtube, and I really wanted to learn how to sharpen knives on a system capable of the sharpest results possible if used correctly. So I made the investment and picked one up. My very first work EDC was a Ruko 3.5" lockback. I recently found it again after losing track of it over 20 years ago. It didn't take long to get it looking and working like new, but the blade edge was so dull and badly folded over it wouldn't cut a worm. It was the perfect candidate for a noob's first sharpening attempt. After setting the sharpener up I didn't use it right away. I went full nerd mode and watched several hours of different tutorial videos on Youtube all week before I put my Ruko in the vice clamp and got started. I took my time and patiently worked my way through all 7 magnetic abrasive, honing and strop panels. As a lifelong musician, using the Worksharp felt a lot like playing an instrument. And the results are absolutely freaking astonishing. I honestly can't get over it. This $15 Ruko knife with a 440 stainless blade is now insanely scary ultra sharp. It clutches fingerprints as if it were sticky. Cuts paper into fine ribbons and effortlessly shaves the hair right off my arm. And the blade edge itself has this unreal shimmering mirrored finish that really pops and captures light. I've also sharpened two more, a Civivi Baklash and a 6" Buck 119 fixed blade hunting knife. Exact same icky sticky sharpness and mirrored edge finish. When the guys at work saw for themselves how insane sharp I got my knives, they brought in 4 more of their own for me to sharpen. This is the pro results sharpener you want. And defi

  awesome knife sharpener.

  I recently purchased the Work Sharp Knife Sharpener, intrigued by its promise of quick and effortless operation. I appreciate tools that simplify life without demanding too much effort. After extensive use, I am pleased to report that this sharpener lives up to its claims.Firstly, its speed and ease of use are commendable. The device is ingeniously designed to make the sharpening process as efficient as possible, saving valuable time. It's particularly adept at honing knives to a razor-sharp edge, a feature that any culinary enthusiast or professional would appreciate.However, there is an area that could benefit from improvement. The knife edge holder, while effective for larger blades, presents some challenges when sharpening knives at a 15-degree angle. This is a crucial aspect for those who prefer an ultra-sharp edge for precision cutting. The holder's design can obstruct the sharpening process for smaller or uniquely shaped blades.To address this, I suggest that Work Sharp considers offering a modified or aftermarket knife edge holder. Ideally, this would feature multiple clamps with a less obtrusive design. Such an enhancement would not only accommodate a wider variety of blade shapes but also enable users to consistently achieve a 15-degree angle on all their knives. This improvement would significantly elevate the sharpener's versatility, making it a more universally appealing tool.In conclusion, the Work Sharp Knife Sharpener is an excellent product, particularly for those who value ease and efficiency in their kitchen tools. With a minor modification to the knife edge holder, it could become an indispensable tool for both amateur and professional cooks alike.

  Great system

  I just recieved the unit today so take this as a preliminary review. If I encounter any issues I will update. The sharpener is packaged in 2 boxes. 1 for the main unit and one for the stones, clamp support, small blade holder, etc. It is well organized and I recommend keeping the accessories box to hold your stones and small blade attachment. It came with all of the parts and grits listed. Assembly (if you can call it that) was very intuitive and only takes a minute or 2. Clear instructions are provided.I had been using a cheap sharpener that works similar to this in general, but the worksharp has so many more features that make sharpening much easier and more effective. When you're sharpening longer knive thaunit tilts back allowing you to turn it without clamping the blade. This is an incredibly important feature as it allows you to keep a consistent angle throughout the sharpening process. This feature is especially important for kitchen knives which tend to be longer than pocket knives. The other feature that I like is the rotating arm which which sets exactly the same when you rotate. There is no guessing or measuring required to stay consistent. The blade clamp has rubber pads so your knife isn't scratched. The clamp is very secure and uses a wheel that you turn to tighten it. There is a support piece that goes below the clap to keep it from moving up and down as you sharpen. I HIGHLY recommend you use it. It's not mandatory, but it will make your edges more consistent. Imo it's a must.Changing the angle is really simple. The unit has degrees clearly marked and you turn a wheel to raise and lower the angle. It also comes with an electronic angle finder which has a cut out on the bottom to fit on the round arm that holds your stone slider. This makes it so much easier to use than a standard flat bottom angle finder. Really nice touch. I bought a laser edge finder here on amazon just to further simplify my life. If you want one just search for it here under lase

  Fantastic system, though pretty expensive.

  This is an outstanding knife sharpening system. At first, I was skeptical. Would live up to the price? I had previously purchased an earlier model from this brand and was disappointed with the results. It simply didn’t perform the way I expected, especially considering the cost.This system, however, is a completely different story. It’s easily the biggest product upgrade I’ve ever seen from a brand. They clearly addressed the flaws of the previous model, because that one had quite a few, and refined everything. The result is a system that actually delivers.I can now sharpen both chef’s knives and pocket knives to a near perfect edge, and I can do it faster and more consistently than ever before. The small design details really stand out, everything feels intentional, ergonomic, and easy to use.If you’re wondering whether it’s worth the investment, here’s the honest answer you can achieve a great edge with a traditional whetstone if you have the skill and patience. There are excellent Japanese stones out there at various price points. But systems in the $50 range, even decent ones, just don’t compare in terms of precision, consistency, and ease of use. This system removes a lot of the guesswork.From a practical standpoint, it will also save you time and money over the long run. Instead of sending knives out for sharpening, you can maintain them yourself. Personally, I do a light honing about once a month and a full sharpening every three months, with a heavier sharpening about once a year if needed. I keep everything at a consistent 25° angle just to simplify the process.For the first time ever, I’ve been able to sharpen a knife to the point where it can shave hair off my arm. That level of sharpness comes down to precision, especially maintaining a consistent angle, and this system makes that achievable.The biggest lesson I’ve learned over eight years of sharpening is this angle consistency is everything, and creating then fully removing a burr at every stage is cri

  Quality, easy to use, amazing results

  Unbelievably easy to get a factory sharp edge. Heck, it might be better than the factory edge as you can chose your angle. I have had a Lansky kit for 20 years. It is adequate for the price but this sharpener exceeds it in every way. Of course it’s way more expensive but here are the pros of this kit: solid, well built. The thing has heft and that is a good thing. Mostly metal construction which is not going to wear out. Precision angle to blade home placement, blade rotates so you can do both shifts without dismantling anything. Pretty foolproof execution. I love it. I put a crazy sharp edge on an old kitchen aid cheap butcher knife that I use for rougher applications and that thing can shave my arm hair off now. I have a lot of high end pocket knives and a few knife kitchen knives. I have only had this for 24 hours but have already sharpened 5 knives. Cons: you really need a case, the box that it comes with is adequate for awhile but is not a permanent storage solution.
