I expected higher product quality. Knife holder does not hold the knife firmly, spheric base also does not hold the position firmly, so knife sharpening process almost was not simplified by the device. Better spend x5 of the price and get tsprof sharpener.
First of all, I think, this is quite nice knife sharing system. But the product I received has some problem. I can’t screw(fix) up the angle indicator because screw of body part(plastic) was damaged. So, I am finding solutions how to fix the angle indicator on the body part.
