Say, that Knish 2 Stage Knife Sharpener works pretty well!

I don’t know how long it’ll last, but this thing is easily worth the $3 price tag. I was able to sharpen 4 knives in a short amount of time. The first stage is really rough and sharpens quickly. The second stage removes any imperfections to the edge. Super nice. Get you one!
