Sauce,
I am glad you called Wusthof. Please post your results. I am not sure WE can go to 11, but I have not tried. In the end you can sharpen to any angle you want. The question is how will it hold up for your use. I am also curious how you feel the edge holds up. I have Wusthofs too, but haven’t gotten around to sharpening them on the WE and am still debate what angle to use.
Besides the Santoku, I use 20 per side for all my kitchen knives (JA Henkels) except for my paring knife which I haven’t got to yet. That was the factory angle for those and has been great since I sharpened them on the WE three weeks ago. Time will tell.
