RUIXIN PRO RX-008 Professional Knife Sharpener with 7 Whetstones, 360° Rotation Flip Design Fixed-Angle Stainless Steel Kitchen Chef Knife Sharpening Kit Abrasive Holding System Tools

Nice that it comes with 3 diamond stones, I will probably use these the most. It is a little difficult to set up, but not too hard, more putsy to adjust. The gripper does a good job, but it would be nice if it had thumbscrews instead of hex wrench. There are 2 sizes of hex wrench, one is a looped T handle, the other is just a normal L type, would have been nice if it was a T also. Adjusting is fairly easy and if you are doing multiple knives of similar size you don't have to reset angle as it will be the same or very close. I could have opted for one that had preset angle stops, but they are ridiculously priced. If I want a different angle with this one I can set where I want. I will also use it to sharpen our modify some of my woodworking tools. For the price, if you aren't doing a lot of sharpening, this is actually a great bargain. The regular stones are good and should last pretty long & the holder does a good job & easy to change to different stones quickly.

This sharpens my knives very well. I'm not a pro sharpener by any means, but I do need cutlery in my kitchen to be nice and sharp. Was able to sharpen an old Cutco chefs knife back to a 15 degree angle and now slices beautifully. Did other knives set fo 20 degree angles and results were just as good.Set up was pretty straightforward, but a few tweaks were necessary. There were some complaints about the whetstones coming loose. This happened to me as soon as I began using it. The stone was snug when installed, but loosened up after a few swipes. The adjustable handle was not tightened to the stone arm enough to keep the stone arm from moving and thus weakened the spring tension on the front stone holder. Once I readjusted the spring tension and tightened the set screw on the adjustable handle to the stone arm, problem was solved. No more dropping whetstones.The other complaint that was coming up was the fixture not holding the same degree when flipping over the blade. On all the blades I was sharpening, it was off by one degree when flipped (others have mentioned 5 or more degrees off, so accuracy varies). Fortunately this variance can be adjusted without a lot of effort. Resetting the degree angle took but a moment to re-adjust to the correct degree using my iPhone level. Much easier than having to remove and then remount the knife. Unfortunately the claim that this will maintain the same angle when flipping the knife is not accurate (at least for my unit). This would have gotten a five star if not for this.I found the construction and materials to put this together are solid and very good. Once assembled and mounted and tweaked, nothing came loose or bound up while sharpening. Using a light touch and letting the stones do the work rather than pressure worked nicely for me. This tool really isn't going to be accurate or last very long if you are heavy handed.Overall, I'm very satisfied with the cutting edge this produces, let alone ease of use.

Unbelievable how great it sharpends a blade. If used correctly!!!

The 3 stones that come with it are nicely backed and fit the handle well however the stones are only marked with a sticker to indicate grit and once it falls off there's no real indication. The additional stones have no backing and fit sloppy in the handle. The device itself is easy to set up and use. I strongly recommend purchasing a compact angle gauge to properly put the correct edge on any blade that's worth the effort of sharpening. It keeps a consistent angle and when used properly works as described. Would recommend

It works great! Got my pocket knife sharp enough to shave with within about 5 minutes. Even was able to do my chef's knife and santoku!Coupled it with a cheap wood backed strop and off to the races!

Broken with in a few mins do to cheap pot metal. the clamp just bends when you tighten down on it. i wouldn't buy this for knifes, it definitely cant do scissors.To work the clamp you have to adjust 5 -7 screws, its tremendously aggravating to work with. I hate this product. i could make a better sharpener with two by fours. I figured it was garbage but i didnt think it would be this bad.

I have been sharpening knives since I was a Boy Scout in the 1970's and I have never had a worse experience. The whole point of this tool is to maintain a consistent angle of the stone to the blade. However, this fails miserably as the cardan and universal ball (the main mechanism that keeps the stone at a constant angle) refused to stay in place no matter how tightly I set the thumb screw -- even with pliers! The worst was where the guide rod attaches to the stone caddie, gripping the rod with barely 1/4 inch grip. No matter how tightly I set the screw, the rod would wobble and work its way free, defeating the whole purpose of the tool by making the angle of stone to blade inconsistent. I sharpened a large kitchen knife, a fillet knife and three small knives. The designers did not consider the small knives and I could not successfully finish the last knife as the universal ball began to bite into the rod and the blade clamp could not keep the small knife secure.On the positive side, there were diamond files included with the stones, which I liked using. There were also a variety of stones for whatever state your knives are in. The packaging was also very nice. It's too bad the product didn't work. Returning.

To say that I have used many sharpeners would be an understatement. From simple stones, to ceramic pull through, to files, diamond headed stuff, and all the "best sharpener in the world" BS. I misplaced my stone set during a move and this item came up with stellar reviews. I will say, the reviews are accurate. There are several great video's online YouTube, showing it's usage. I have had it under a month and have sharpened, several knives and scissors with it. Simple to use, accurate and efficient.
