Iki Ruixin Pro™ Sharpener + 4 Whetstones Set

The supplied sharpening stones are soft and dulled my knives more than they were before using them. High quality stones that fit the his tool are NOT readily available and very pricey. There is no app to check the angle. This should be clarified in your marketing. I have a tool that is well built but not whole. The stones stink

Not as hard to use after learning how to use just do as the directions say to do 👍

It’s not easy to use with smaller blades other than that nice sharpener.
