Input:
I am truly impressed with this knife sharpener. Finally I can sharpen all my knives including serrated knives, and knives with smaller blades that I couldn't get a good edge on with my honing steel. The directions were easy to follow and super descriptive, not only on how to use the sharpener but also how to extend the life of the sharpening blades. Very little pressure is needed in order to sharpen the knives making this a safe option for novice cooks and knife hobbyist's. Now I can trust the rest of my family to sharpen away without ruining my knives!
