My house has 5 adults, all cooking, cutting and preparing meals on a daily basis. I purchased this sharpener to give to my son and his fiancée so I would not have to keep sharpening their knives. It has worked very, very well and is one less chore I have to do around the house. While there are other handle designs out there that I like better, I and they, are still very pleased with this one. This product does work as advertised and deserves 5 stars.
The “Course” side contains carbide blades fashioned at an angle similar to how a crock stick is done. The angle is not mentioned but looks like it could be 40 degrees which is also pretty standard on a crock stick. The “Fine” side is two ceramic rods which appear to be at the same angle as the course side.
I have used this to sharpen about a 6 – 8 knives. It works surprisingly well. This sharpener is NOT for scissors or serrated blades.
