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

Why buy an overpriced copy, when you can own the original one for half the cost.

This sharpener is able to get a razor sharp edge if used properly. the instructions were written by someone who clearly did not speak english as a primary language, but they are decipherable and provide great guidance on how to use. this is the second model i bought because the first one was made of mostly plastic, which became brittle and collapsed. this one is made of metal and has held up much better. four stars because i broke 3 stones using tis when they fell out. the beveled stone clamp does not hold a stone properly unless i was shipped this short a part. if you are very careful this can be prevented.

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.

The system is good. Has some learning curve but that's expected on any system. The stones, however, are really cheap. When opening them, I could see the quality was not all there. They are thin and flimsy. The spring on the stone arm isn't long enough to apply a lot of pressure, but you're counting on a hand tightened metal surface holding a wet stone. Needless to say, it slips all the time. With that, I have to stop a lot more to fix the stone, make sure it doesn't get stuck, make sure it doesn't fall, etc. Inevitably, one fell and you can see the results in the picture. Now I'll have to wait, get new stones or diamonds and try again. What was supposed to make my life easier and help speed things up, only slowed it down. Took me about 30 min to do one knife and it's not even that sharp.

Absolutely amazing. Mine came with 8 stones and the set up is really solid. I have gone through and sharpened 4 of my knives with it and the edges are holding extremely well.

I don't take time to review anything unless I hate or love it. and I absolutely hate this. the instructions are just confusing and incomplete. you can't even set the angle to sharpen to without some sort of device or phone app. any knife sharpener should not need some sort of external device or to download an app to use. and if it does it should be made clear in the description. It comes with whet stones that should be soaked in water before use, the instructions do not say anything about that, so anyone who managed to get through the assembly procsess but has never used a whetstone would not know that. I personaly didn't have the patience to finish getting it put together plus find a way to set the angle. I watched a video of someone using it. so it works but the person on the video said its garbage. I am a chef so Its important to me to have sharp knives. I have always just used an electric sharpener. they have there shortcomings but I don't consider this an upgrade at all. so I hope the time I took to write this helps people to know what there getting into if you buy this.

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.
