We bought this knife 3 years ago, and it is still razor sharp. The handle is smooth and ergonomically shaped, knife is well balanced and a pleasure to use. The grooves ensure that the blade doesn't "stick" in whatever it is that you are cutting. Exception to that rule is soft cheese, but then this isn't the right tool for the job of cutting soft cheese, is it? Highly recommended.
I would recommend this product to a friend.
