Though I have not used all of these knives, the ones that I have used are quite impressive (sharp & easy to handle). I am curious to know why each knife is designed the way that it is, like if they are for a specific purpose. I have not looked for that answer, I just use them wherever I see fit. I purchased these because my parents and sister enjoy their sets, and the price was right for when I purchased them. One of the more wiser acquisitions that I made this past year.
