I recently got a set of Wusthof Ikon knives. I read on these forums that they have a 17 degree edge. However, I called Wusthof and they said that the Wusthof Ikon kinves have a 20 degree edge, and the only Ikon products that have a 17 degree edge are the Ikon Santokus. Does anyone know who is right? My experience is that customer service reps don't always know what they are talking about, so I figured someone here would know the truth. I am asking because the set came with a free Wusthof Ikon manual sharpener which has the same Ikon handle style but I don't know what angle it is set at since it did not come with any manual or documentation. Thanks for any help.
