Review title: You can sharpen a blade with this.
Product review: I own a couple of these sharpener and I think they work great. They work best on a factory edge. They work so well on a factory edge that you can shave the hair on your arm. I find if I use it on an edge I've been using a stone on and have achieved a good polished edge it doesn't work as well. I think that is because my hand sharpened edge is rounded and polished. The rounded and polished edge just slides right through the pull through sharpener. So, if you have a knife with a factory edge it works great and it works great for a utility knife.
