Knife Sharpener with 10 Whetstones

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.

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.

All my kitchen knives are kept sharp, with this device I can take them to extremely sharp to just plain ludicrous! It takes a while to learn how to achieve the best possible edge, but once mastered the results are remarkable. The over all quality and construction is very good and should last a long time with proper care. Beware, changing stones should be done over a table, they are long and thin and will not survive a fall to the floor. Note: ludicrous level will actually shave hair off ones skin, but is not good for kitchen use as the edge will fold easily and go dull. Very hard knives take a bit longer, but the edge lasts a long time.

We really enjoy using this sharpener. Once it is set up, it holds the proper angle and makes razor sharp knives. 3 stars because the stones wear so quickly. They must be cheap. After a handful of kitchen knives the coarse grit stones are almost gone.

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.

a Chinese product that doesn't work

Très bien

Bueno

This was great for sharpening my knives. Is does leave stone dust on the floor but that is to be expected.

Everything is work, but the sharpening stones are poor quality
