Upgraded RUIXIN PRO RX-008 Professional Knife Sharpener with 10 Whetstones, 360° Rotation Flip Design Fixed-Angle Stainless Steel Kitchen Chef Knife Sharpening Kit Abrasive Holding System Tools

Overall works great. I bought the metal upgrade swivel for this do to some complaints on longevity on original swivel. I can't attest to that because I upgraded it right away and kept nylon swivel as a back up. I usually use a wet stone and hand sharpen by feel and eye. However, that can be tricky and time consuming. This hasn't sped up the process that much for me, but it does keep a consistent angle for the knife bevel. I also bought a competitor diamond stones with similar size plates. They actually fit the RUIXIN PRO RX-008. I chose diamond plates for when I need to re-bevel and shape a severely chipped or dull blade. The stones are not bad but those are better for maintenance sharpening and upkeep. Where as diamond allows you to reshaping and re-bevel really dull blades. The key to sharpening is that you have to shape primary edge first then Secondary edge (cutting edge) last. I could be using the edge names backwards, however, the point is for extreme sharpness do as follows: 1. Make sure blade is straight, not bent. 2. Thin out main edge a little. To do this pick a flatter angle than cutting edge angle. For instance let's say you want a 17 degree cutting edge. On this step you sharpening or thin to a 10 degree angle. 3. Now that step 2 is done you increase angle to 17 degrees and sharpen. What I do is clamp down blade and bevel edge evenly until my nail catches a burr on opposite side of blade. Then I unscrew the blade turn over and repeat. Depending on the dullness of the blade will determine what grit to start with. If your knife is really dull you want to start at lower grits and slowly move up to next grit. At the very end use a flat strop or straightening chef hone. This will remove small burrs and straighten the cutting edge (pretty much microscopically). If you can see the burr with the naked eye that is not good. Also, One last thing do not use the clamp swivel clamp for sharpening (meaning pick a side to use. ) personally I chose hexagonal (allen wrench screws up). Even though this increases the sharpening time, it does two things for you, keeps same angle, if you flip clamp angles are different. So unscrew blade and manually flip blade and re-clamp. This Keeps you safer and keeps same angle. Because if that spring loaded part were to give out while you are pivoting it you could severely cut yourself. The swivel is for choosing an angle not for flipping and keeping same angle. If the design is for that than I'm sorry it will not work as intended. That being said as long as you manually flip blade and re-clamp you'll be good with this.

Works as intended. The whet stones will break if dropped, or handled roughly. None were broken in shipping, but one did break when it was accidentally knocked off the counter. A little hard to get use to, but once your set its simple. Id rather a classic stone, but works all the same.

Impressive. Disclaimer, I didn't use the stones. I went straight to the RUIXIN PRO 8 Pcs Diamond Knife Sharpening Stones sold in here and sharpened 5 knives in an hour. The reason it took that long is these knives haven't been properly sharpened in a decade and were closer to hammers than knives. Three of the knives were Shun Classics which are my wife's favorite. I can't say I know how she did it but one of them had several 1/16th or bigger chunks out of the edge. I didn't have much hope for that one but I stayed on the lowest grit in the diamonds and basically removed a 1/16th all the way along the edge. Worked great, but took a bit. That one knife was easily half an hour. All of the knives easily pass the paper slicing test. Pretty impressive at the price. Yes, it's all a bit finicky and you have to wash all of the china off the parts to get them working properly (I used wd40). The collars can move and change your angle if you're not careful with them and I suspect if you have no mechanical knowledge at all this could be tricky but all in all I don't regret the purchase.

Kind of a pain to setup, should have some type of simple way to attach the knife vs having to use small hex wrenches. Setting the angle with a "digital angle" app on your phone is also a pain, couldn't find a protractor in the house. You need it if you want a 17 degree angle for filet knives. The stones are rather small and I think rather brittle. I dropped and broke the 400 grit while putting into the holder. The part that holds the stone is anything but secure. It put a decent edge on some of my knives, but I find it's way simpler to just use a bench whetstone with an angle guide. I wouldn't have bothered ordering one had I known what I know about it now.

Excellent tool! You are going to be catapulted into a time long gone in Japanese history. Note: this tool requires patience and endurance. This is not a quick fix to get your $ 10.00 Chef’s knife from totally dull to razor sharp in 5 minutes. However, if you know what honing oil is, know the fact that any sharpening stone used in machine shops are brittle and enjoy sharpening even stainless steel or high carbon steel to a surgical scalpel finish, which will take several hours, then this tool is for you. I got the standard stones, which arrived in good order, watered the ones I needed to use for a dull low end carbon steel Chef’s knife and carefully assembled the tool. Check the hex head screw on the back of the knife holder. If this screw comes loose then the knife holder may come apart, which has apparently happened to other reviewers. When inserting the knife in the holder loosen all 7 hex screws and insert the knife straight. By tightening the screws in a pattern, you can get the knife installed so the angular misalignment is less then +/- 0.2 Degrees when turning knife during sharpening. I was able to minimize the error by adjusting the knife seating in the holder to about +/- 0.1 degrees which took about 20 minutes and required a great amount of patience and a very steady hand. A Japanese Master can do this probably in a couple minutes, but I am an apprentice in this. Also, the angle has to be checked and readjusted every time the stone is changed to next higher grid. The more time one spends on adjustments, the better the results. After all, practice makes perfect.

Unfortunately, I was very disappointed with this knife sharpener. The biggest problem is that it simply did not sharpen my knives very well. After using it as intended, I wasn’t getting the kind of edge I expected, which defeats the main purpose of buying a knife sharpener. More importantly, I found the design concerning from a safety standpoint. Sharpening knives already requires some care, and I didn’t feel comfortable or confident using this product. A knife sharpener should provide enough stability and control that you can focus on maintaining the proper motion without feeling like you’re putting yourself at unnecessary risk. Between the poor sharpening results and my concerns about using it safely, I stopped using it. There are better sharpening options available that provide more control and produce a better edge. I would not recommend this one.

What I like: 1)The pretty secure mount to a table, etc.. 2) It has 2 long matching metal plates that uses more than 3 bolts for upper and lower knife adjustments and it secures the blade very very well. 3) It is very easy to use once you get it set up, preferably next to a water source for keeping the stones wet. 4) You can get the blades of your knives razor sharp. 5) It is just a matter of pulling to flip the knife over to the other side safely. What I don't like: 1) It takes time and patience to get this set up. But once it's set up, it easy to use. 2) I am going to switch out many of the bolts so they will be easier to use and tighten. I have to use a pair of pliers to get some of them tight enough to hold for any long time use and maintaining a constant angle. 3) It's tricky getting the angle you want. I down loaded an app on my phone to get the angle then I made scratch line where when I set it up again, I would have the angle I want. 4) It's a little pain in the tail screw and unscrew the bolts when changing knives, but it is what it is. This has got the most secure blade holder you can get.

I got this to replace my Lansky system that functions basically the same way. This system offered a few improvements, so I figured I would check them out. I must state that I also bought the upgraded swivel joint and the upgraded diamond plates. My Lansky sucks for pocket knives. It also struggles to hold any knife in the clamps. There is a tiny notch they are supposed to go into and it pinches down. What usually happens, though, is that the knife will start to wiggle free as there is not enough clamping surface area to adequately hold the knife. This system has a MUCH larger clamping surface. This system has a C-clamp mount that lets you attach it to tables or counters or workbenches. That is also a huge upgrade. The Lansky has predefined angles you must use, which of course actually change with the size of the knife. So a 17* is not always 17* if the knife blade is wider or narrower and for pocket knives, it was just awful. With this system, you can adjust the angle to anything you like. This was my number one reason for upgrading to this system. For the item out of the box, it gets 4 starts over all with a few 2 star features: -The stones do work but they are VERY soft and do not work well. You definitely want to upgrade to the diamond plates. -The swivel joint works just fine and I probably did not need to upgrade it, but the pro joint does work better. So I am not upset that I got the upgrade. -The plates that hold onto your blade come with some protective plastic clips that attach with double sided tape. These are crap. Just throw them away and get some masking tape. It works just as well at protecting your blade from scratches and does not wiggle around like the plastic pieces did. Once I made those modifications, it is a truly incredible sharpening system for any purpose knife from pocket, to bushcraft, to kitchen. Just do not forget to take a leather strop to your edge when you are done.

good

a Chinese product that doesn't work

Très bien

Bueno

Everything is work, but the sharpening stones are poor quality
