Review on Enhance Knife Performance with MOVIRON Professional Knife Sharpening Kit System, Stainless Steel Chef Tool Set Including 4 Whetstones & 3 Natural Stones by Carl Lipschultz

Easy assembly and operation - that's the only plus. The difference between one side and the other is about 5 degrees and doesn't really repeat itself (at least not close enough, you have to correct the blade shape every time you pick up and put the knife back on). This is really far from a precision tool that a sharpener should be. Unfortunately I missed the return window, luckily it wasn't as expensive as that fake Japanese knife site where they sell the exact same thing for 4x the price which is ridiculous (this one is heavily promoted on social media which is everywhere are where you're going)
