Great tool
Really enjoying using this sharpener and it works great. I could have spent more on a bigger more professional setup but for my purposes this does the trick just fine. It’s compact so it stores easy, quick to setup, and has smooth operation. Got all my knives nice and sharp fairly quick. Three things to make it better- the base could be a little heavier so it doesn’t rock as easy, the clamping system could be a little more secure, and to sharpen a larger knife you really should use a larger sharpener but it works if you sectionalize the knife. I’ll get a kit of use out of this thing.

I'm impressed
My old Smith's guided sharpener started really showing it's age when I tried to sharpen my pocket knife the other day and the stones started falling off of their holders. So, I came to Amazon and started shopping and came across the Work Sharp Precision Adjust Knife Sharpener. I read the reviews, looked at some online videos, popped over to YouTube to see how it worked and what testers had to say there. For under $50 it sounded like quite a bargain, so I decided to give it a try. A couple of minor quibbles - 1) the clamp that grips the blade could stand to grip a little better. It's good enough, and since the sharpening process requires very light pressure (you basically let the weight of the "tri-brasive" do the work) I had no problems with my knife slipping, but it just didn't feel really secure. 2) It could stand to have some more abrasive grits. I found the 320 grit (coarse) diamond hone adequate to true my blade up, and the 600 grit (medium) diamond hone did a pretty good job of sharpening. The ceramic hone would probably do a great job of polishing the edge if you wanted to spend a LOT of time with it, but a grit between the 600 grit and the ceramic would make it a lot easier and faster to get a good polished edge. I ended up with a VERY sharp blade, but you can still see the abrasive marks from the 600 grit after making the recommended 10 passes with the ceramic. Add an 800-1,000 grit in there, and a strop for after your done with the ceramic and you'd end up with a ridiculously sharp blade. The build quality seems quite good. The sharpener feels sturdy and solid, and I had no issues with it moving around when I didn't want it to. Assembly and disassembly is a breeze with the exception that the snap on base is a challenge to unsnap. The parts all work as advertised, and I took a knife that had a somewhat abused edge and ended up with a very nice, flat bevel that feels very sharp. Not quite razor sharp, but close. For pocket knives and kitchen knives this sharpener would be very hard to beat, especially for the price. It is definitely far superior to most of the knife sharpeners out there. If you decide to give one of these a try look for the Aenllosi zippered hard case that's designed to fit this sharpener. When I ordered my sharpener there was a link to it right on the sharpener's page, and it was well worth the $14 or so selling price. It has built in wells for all of the sharpener's components when disassembled, plus a mesh pocket to hold the tri-brasive and rod. Very nice quality item and a perfect fit.

I suggest you get the upgrade kit as well
I have a few knives for EDC and for my workshop, as well as the usual kitchen knife set. I’ve never been happy with the performance of my little Smith’s 2-step, coarse and fine, knife sharpener. I’ve tried using a stone and failed miserably. . After field dressing a deer, this Fall, wishing all the while my knife was sharper, I decided to check out some knife sharpener reviews on YT. The Work Sharp Precision Adjust seemed excellent value at just $60, had great reviews and was simple to operate. I ordered it. . The Work Sharp Precision Adjust is indeed very easy to use. The knife holder has some flexibility to it but to use this sharpener correctly, you do not apply pressure to the stone on the blade. Let the stone do the work. You just move it back and forth. The flex therefore becomes negligible. . My first attempt to sharpen my fixed blade deer knife was good but disappointing in that I couldn’t slice through a sheet of paper. It was sharp but not the promised sharpness. I couldn’t establish the original angle off the cutting edge since I’d changed it with my failed, manual, diamond stone sharpenings. I essentially had to reprofile the edge. This is where I found the Work Sharp Precision Adjust was lacking. It took forever with the lowest grit of 320. Eventually, I sort of got there. Same with my next knife and similarly with my small kitchen knives. All needed some reprofiling. A day or so later, after watching yet more videos, I revisited my knives. This time, I was able to spend a little less time and managed to achieve that awesome paper slice. I think I was able to refine the new profile this time, having remembered the angles I’d used, and didn’t get frustrated like the first time. I also used a 15x loupe to see the edge detail. That’s now a permanent accessory in my sharpening kit. . I concluded that 320 grit was just too fine for an effective reprofile, especially on a longer knife, or one heavily chipped. . I considered returning the $60 Work Sharp Precision Adjust and buying the Work Sharp Precision Adjust Elite kit for another $60 more. The coarser 220 grit included in that kit would no doubt make reprofiling a lot quicker. Then I reckoned that it was just as cost effective, if not more so, to keep what I had and order the upgrade kit. Yes, that is $80 more. However, I keep the existing 320/600/ceramic sharpener from the original Adjust, adding another 3 sharpeners, with one set being an extra of what I already have. You can order new stones for around $7 each. So, I’m actually getting a spare set of 320, 600 and ceramic stones, including another holder, for only $20, versus over $21 for just three individual stones. Better value to spend the $140 for the Adjust and the upgrade kit than the $120 Elite. . Tonight, I used my now-upgraded kit on another folding knife I keep in my truck. I’ve never sharpened that one and it was pretty blunt. I used a Sharpie pen to help establish the cutting edge profile – 25 deg. Starting at 220 grit, it didn’t take long to make the first pass. I moved through each of the stones, refining the edge each time and finished off with the strop. I already have a large strop but the Worksharp strop, keeping the exact edge angle used to sharpen, makes the final step a no-issue breeze. You won’t easily get a mirror polish finish, (that will take more time with the finer stones and ceramic) but without the loupe, the cutting edge looks shiny, clean and it’s razor sharp. That’s all I’m after! . I think that, for the money, this is one of the best sharpeners out there. It’s easy to use once you try it a couple times, and the results are awesome! I do suggest you get the upgrade kit though. Whether you buy the Adjust plus the Upgrade kit, or the Elite itself, you will need those additional stones for reprofiling with ease.

Easy to use. Highly effective and high value. You'll be happy with the results.
I came across this thing as a fluke and was intrigued. I had a Lansky years ago that I just could not get results with and I ended up giving it away and thought this was a retread. Conceptually it is the same. You lock the blade in place and the abrasives are guided, leading you to a consistent and clean edge. This entire set up is just easier to use. I added the lapping films and feathering adhesive and was very impressed with the results. I sharpened a PM2 with an S30V blade and a TAD Dauntless with an S35VN blade. The PM2 was a bit tougher to line up due to the blade shape, but once I realized the key was consistency, I locked it in and started at 20 degrees. From there I fine tuned the blade and took it through the ceramic stone and was very impressed with how well the knife cut. You develop a rhythm and technique and it does have a "feel" component. Once you feel a burr, flip the knife and do it again, hopefully near your first count of strokes but if you lose count, raise the burr on the other side and go to the next abrasive. It really is easy to use and the ceramic plate as the finest grit will be perfectly okay for most people. That will be the sharpest knife they've had or done themselves. If you want to go to the next level, using lapping film on the ceramic stone is easy and very effective. I took it to a 2500 grit and got a mirror polish on both the Dauntless and the PM2. The change in how the Dauntless performed was amazing. Using the films and adhesive on the ceramic stone is a great upgrade and very simple. A pack of the films is right around 4 bucks in the Wal-Mart automotive section, and I also bought as part of the package here. Not every edge will require a polish and the system is flexible enough to let you try some things with angles and varying grits on different parts of the blade. There are some things this sharpener is not designed to do. That said, for smaller blades, kitchen knives, EDC, etc., it is easy and effective. For larger blades, tools, scissors, and odd shaped blades, that is why you have multiple sharpening options, right? For some items you just can't beat free-handing on water stones, or the guided bench sharpener from work sharp, or even a Sharpmaker For the two knives I sharpened here though, and I did it right out of the box the day I got the sharpener, I've never put a polish on an edge that fast or that well. I also don't think I've ever made a blade edge that sharp. This is not a gimmick and it works well. ————-update 1 May I just finished a ZT 0562 CF with a CTS 204P blade and it put a very nice edge on. Setting the edge with the 320 grit plate took a while, and I relieved the shoulders using the 15 degree position before going to 20 degrees. Once done, using the 600 and ceramic took it to not-quite polished but much sharper than out of the box. Getting a burr took a few minutes but once It was raised, honing it down was easy. Very impressed with the performance on 204P.

Great Product
Absolutely love this Device. Able to keep all the kitchen knives sharp. Works extremely well. Had one problem after about a year of use. The thumb screw to tighten down to hold the blades stripped out. No telling how many knives it had sharpened up to this point. After checking their website, found out that i could buy a replacement piece. I did that and the shipping for the replacement part was fast.

Money well spent!
I'm not easily impressed with Chinese manufactured goods. 99%of it is garbage. Worksharp is an U.S. based company that holds their partners to task. Im not saying that this sharpener is without issues by any stretch. What i am saying is that for what it cost me, it's awesome! If you're considering this tool, you've likely seen the "wicked edge", I think it's called. It will run you a thousand dollars plus, fully dressed. You can make a living with that professional grade tool. Don't expect the results to be in that league. You have to coax it out of this one. By that I mean, you can't lean on it aggressively while sharpening. The mechanism that clamps the blade is cool and all. It allows you to remove the blade from the tool while remaining clamped to help maintain the angle. You can also spin the blade from one side to the other with a positive lock in the detects. The issue is a little disappointing really. Its held in place by a set of magnets. Okay. The real problem is with the part of that mechanism that in my opinion is the most critical in its function. The part that is supposed to provide rigidity and precision is pretty lame. They chose to have the part that is worked the hardest made out of a minimal amount of plastic. They didn't properly counter the amount of leverage involved. Each stroke of the abrasive comes with an excessive amount of downward pressure and an unacceptable amount of deflection of the blade. Instead of crisp angles you get a rounded over edge. This is where the coaxing part comes into play. With patience and by gripping the clamp just so, a razor sharp edge can be produced. Hence, all of the little hairless spots on my forearm. All said and done I think the next version of this tool will likely address this issue. Hopefully they read reviews. Should you buy one now? Hell yes you should! Ha! I love it. It would be even cooler if they sent me one of the new and improved versions when they roll them out. Hint hint...Lol!

Quick, easy, and produces a quality edge
For a guy who has been carrying pocket knives for nearly 50 years, and who has a huge collection of Bowie and other classic blades, I have always been utterly pathetic at sharpening knives. I don't know what it is, I've just never been able to do it correctly. At least not to the point some of my extremely-expensive blades warrant. I've also tried multiple sharpening tools and systems and while some of them do work to a limited extent, I've never found one that worked well enough for me to trust anything but cheap kitchen knives to them. And then I bought this thing. My first job was on a big Spyderco folder that has been dull as a butter knife for years. I've tried sharpening it but have never succeeded beyond a mediocre edge suitable for nothing beyond cutting cardboard. And I'm not going to risk totally ruining such an expensive blade. So I put it on this Work Sharp tool and in about 30 minutes, to my amazement, I had an edge that I was giving myself a nice case of knife-fighter's mange with it. Meaning it was shaving my arm like a razor. It has a consistent bevel and will be a breeze to maintain from this point on. Next, a Shun chef's knife that cost a fortune and has been in a drawer because some jerk in my household some years back used it like a utility knife. Like the Spyderco, I wasn't going to risk ruining this thing by using any of the other unsatisfactory sharpening tools I have. But had it shaving too, in no time. And so it goes. Finally, in my old age, I no longer have to suffer the shame of being a knife fanatic and collector who can't sharpen a knife to save his life. This Work Sharp system is fast, uncomplicated and easy to use, and produces dangerously fine edges. I can't recommend it highly enough. Next I'm going to purchase the upgrade kit for it and my edges will be even finer. I'll probably cut a finger off.

It gets the job done for a reasonable price
This is a great sharpener to get started with. It will sharpen anything that most people own. It is easy to adjust the sharpening angle. The 3 grits that come with it are enough for anyone other than someone who wants a mirror blade. If you think you need more than an the ceramic stone that comes with it for general use, you are wrong. Although it takes some adjusting of the blade you can do very short blades as well. In the photos you can see a Civivi Baby Banter. It does have a few flaws that are easily resolved. 1. It needs to be bolted down, secured with some clamps, or you will need to hold the base down with one hand while sharpening. This is more of an inconvenience for someone how will use it in different locations around the house. 2. You can't sharpen blades over 12" and to be honest over 10" is a little on the extreme. 3. The sharpening surface, 4"X.5", makes sharpening take a bit longer. It would be nice if you could use the 6"X1" stones that are standard on the Professional Precision Adjust and most other systems, i.e. Hapstone and TSPROF. This is more of an inconvenience as well and if you didn't know about the larger stones you wouldn't be missing anything. 4. ***This is the BIG ONE*** Because this is made out of Plastic there is some flex and the longer the blade the more there is. I feel like this should have been addressed by Work Sharp but you can find braces on ETSY of all different shapes and designs. I went with one from Create Sharp who also does lapping films. - See Pictures.

Cumpre o prometido
Produto cumpre bem a promessa, é fácil de manusear e de fazer a manutenção, tem que ter um pouco de noção de como fazer, só achei o apoio um pouco “mole” mas nada demais, coloca uma rolha em baixo que está tudo certo. Quebra muito o galho você ter a geometria do ângulo, ainda mais pelo perfil de corte ficar alinhado o que na pedra é necessário muita prática, experiência e noção. Recomendo, acredito que desses afiadores guiados de inicial é muito bom, muito melhor que os chineses mais baratos, claro, não é um Lansky nem um KME, mas cumpre muito bem !

Works amazingly well.
I tried to learn hand sharpening on a water stone and after a few years of not really being satisfied with the results (knives were sharp enough to slice paper, but could struggle with a tomato skin) I broke down and got this guided sharpener. Even after my first use it got my knives sharper than I've ever been able to manage on the water stone. I'm sure there's better guided sharpeners out there that maybe can be attached more securely, hold the knife a little better (it's adequate as long as you don't get too rough and securely place the knife in), or have easier to use sharpening rods (they're a little skinny so you have to be careful not to rock them). But for this price I doubt you're going to find a better one. I also can't speak much to the longevity of the sharpening surfaces, but for light use I'm sure they'll last decently long. Works on pretty much any hard surface, you just have to hold it and be a little careful. Comes apart relatively easily and can store back in it's packaging.

Super Afilador
Es un afilador sin igual, simplemente magnífico. Es posible afilar navajas y cuchillos medianos a grandes; las pequeñas navajas Vicrorinox no es posible, son demasiado chicas. El control del ángulo de afilado no tiene igual, yo afilo la mayoría de mis cuchillos a 25°; rara vez afilo a 15° o 20° y prácticamente nunca a 30°. Todo esto es posible con este afilador. Este equipo es delicado, no me parece de uso industrial, para mi es suficiente. Me gustaría tener una gama mas grande de piedras ahora solo tengo los que vienen en la caja, 320, 600, 1200. Será necesario conseguir algunos granos intermedios.

The best but not perfect.
By far the best sharpener ever, it's genius... Unlike Lansky, this can adjust angle at precise setting also while hitting the curves. What could've been perfect, an option to get different grids/spare "Tri-brasive" rods and bigger clamps. I find inconvenient sharpening one of my hunting knife (thick and chunky spine) I will definitely buy another regardless Work Sharp wants to update their product or not.
