Query: Serves It's Purpose

So far so good with the Kapoosh. I got it as a gift and have put it to use with my new knives as well. I do get the feeling that this may dull knives much faster but time will tell. It also gets more and more tough to get knives in at the beginning but will loosen in time. It has been good so far and plan to continue use. If it does start dulling though, I will be pulling the block that came with the knives out.
