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.

Excellent sharpening system
Price was reasonable for the quality of the sharpening system. Assembly was super simple and the instructions provided great insite as to how the system works. The operation of the sharpener was easier than anticipated. The 3 tristones that came with the elite work great. The time it took to sharpen was not bad considering how dull one of my knives were. I needed an upgrade to my current sharpening system( it was a hand held where you spun the wheel to choose the rods to use). Didn't like that one since the day i bought it. This was an excellent choice for a sharpening system. I would even go as far as saying a complete novice would be able to get a great edge on any knife with minimal effort. I will be using this on a regular basis. Not sure if i can get replacement parts though( the trisharp stones, or any part that may break or be consumed)

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.

Sharpening knives has never been so easy before
My mother and I collect a ton of knives, though as far as sharpening them I’ve never really paid much attention to. I’ve noticed a ton of them beginning to be very dull, so I purchased this since I don’t like any of the other sharpening tools I have. Man it’s so easy to use, you can set your angle so easy and just get to work. Can sharpen quite a few knives quickly with this. The quality is great I was concerned about the magnet but it’s solid as heck I’ve had no issues with large knives or small knives. I highly recommend this product.

After a little practice, I got the sharpest edge I've ever seen!
I've had this system for about a week. I finally had some time to sit down and set ot up. It's extremely easy to setup, and has a great little case that everything fits neatly into. I glanced at the instructions, watched a fee YouTube videos, and got to work on a cheaper knife I've been trying to sharpen by hand for days to no avail. This knife wouldn't cut paper and was giving me a headache from trying to sharpen by hand. I started on the courses grit and finally got a burr after about 20 minutes. It was starting to give me another headache, but I kept at it. It takes a little time to figure out the technique and proper form. But, once you get it, it's amazing. I worked through every grit, and the strop. The edge almost had a mirror polish after my first attempt. It was getting late so I started rushing through some of the stones once I got the hang of it, or it would've had a real mirror polish. It is by far the sharpest knife I've ever held or sharpened. Blows away every factory edge ive ever felt, all 38. I have a few other systems, much cheaper, and not diamond stones either. One is more for touching up your edge. I have tried free hand sharpening quite a few time, and every time have ended up with a more dull knife than when I started (I'm still not giving up). It's very refreshing to know I can put a razor-sharp edge on any of my knives now. This system has everything you need and is easy to use. You get great results, and the price is very reasonable considering the costs of other fixed angle sharpeners. The build quality is great, the clamp hold the blade secure. The only thing I can recommend is a digital angle finder, got one for $25. Also, at first feel the stones didn't slide very smooth on the guide rod. So I put two drops of gun oil on the plastic where the rod touches and that greatly improved the feel when sliding the stones back and forth on the edge. Lastly wipe the blade between grits, and get an old toothbrush to clean the metal out of the stones to prevent cross contamination between grits. Also, I highly recommend watching some of work sharps YouTube videos and reading the comment section, thats where i heard about the oil and cross contamination. There are different techniques that can yield different results, work sharp has video on that. Overall for the price I'd go with the elite version, but I'm sure the basic would work great, except when it comes to the mirror polish.and final look. I'm am blown away and extremely happy to have a system that not only works, but works great!!

Wicked sharp!
Fantastic product! It arrived at 4:30 AM (early delivery) and had it setup within 10 minutes. Sharpened my favorite Benchmade EDC folder in about 15 minutes, including stropping the edge to a razor sharp mirror polished finish. The secret is the blade holder which can clamp onto and securely hold shaped blade profiles, something no magnetic holder can do. The only downside is the swing arm stone holding mechanism can only reach short (6 inches or so) knives in one pass (a release and re-clamp is required). All my longer blades are flat-sided kitchen knives, so my old magnetic holder / rolling stone works fine for them.

Absolutely Outstanding Sharpen
This is hands down one of the best knife sharpeners I’ve ever used. I’ve tried whetstones in the past, and while I could get a knife “sharp,” I could never truly grasp maintaining the correct angle consistently. Because of that, my results were always hit or miss — sharp, but never this sharp. With this sharpener, the difference is night and day. The guided angle system takes all the guesswork out, and the results are honestly machine-sharp. I’ve never had pocket knives this sharp before. I actually have to be extra careful now, because the edge this puts on a blade is no joke. Even the V-block comes with an insert that literally says “You will be creating incredibly sharp knives. Please handle with care.” — and that ain’t no joke. Just following the system gives you a dangerously sharp edge. The process is simple, controlled, and repeatable. If you’ve struggled with whetstones or inconsistent results in the past, this completely solves that problem. Fantastic tool. Worth every penny. Highly recommended.

Quick. Accurate. Easy. Angles aren’t just fisherman anymore.
This works great and it’s easy! I didn’t take much math growing up and don’t really know why angle is important in anything other than a divorce lawyers playbook. Unless we’re talking about the angles my ex wife was taking while out with her “co worker”. My knives are sharp and it’s doesn’t take long to get one sharp or swap out stones. I had the Ken Onion edition electric sharpener but this is easier and less messy as well as simpler to use. I’d argue it does a better job as it’s easier to control the amount of material you remove. They call me Kurt now these angles are so good. Heaven must have sent these angles. Ok no more angle puns. Get one if you want sharp knives.
