Query: Wow, these are sharp!

This knife set is exactly as described. They are super sharp, so definitely be careful with cleaning! They cut through most items really well, although you will still need a serrated knife for some food (ex: tomatoes). I have only had these for a few months so I can't comment on how long they stay sharp or my experience/cost with getting these sharpened. However, I did learn from other reviews that you need to send this in to be sharpened and cannot sharpen this on your own.
