I bought this item as I have many other Ninja products in my kitchen. I know Ninja items are quality and function as advertised, so the Ninja Premium Knife System 12 pieces set does not disappoint! The extreme care taken to ensure the purchaser does not injure themselves unpacking the item to the sleek already pre sharpen knives (unpack slowly) was geared to the customer safety. The best is in the handling of slicing items… cuts through meats like butter!
