What an awesome set of knives!  These

Knives has two sharpen spots for different large and small knives. I love the large knife for cutting potatoes and apples because it doesn't stick to the knife. The knife cuts with ease for and even cut on the potatoes.  Any cutting task is now easier with these knives. Only thing I don't like is that the set has to shapen often which I don't like.
