Not sure as I us d to have mine done by a traveling sharpening dude that would be at the farmers market in from of Otools nursery on wadsworth. I recently purchased thus sharpener and it is simply awesome. Kitchen knifes are like razors and have durable edges. Pocket knifes the same. Super easy to use too ! May be something to consider.
