From personal experience, don't be eager to sharpen your Yoshihiro stainless just yet. I know, looking at Jon's videos it seems an easy task to sharpen a knife, but you need some practice first before you can touch that blade.
I would recommend that you get a cheap soft carbon knife and learn how to sharpen, first. This will be an inexpensive and easy introduction to sharpening. Once you gain some skill, move to Henkel's and feel the stainless steel. That's my opinion, but it might be wrong. Hence I encourage others to chime in.
My first Japanese knife was Fujiwara Kanefusa FKH-2 purchased from JCK website here
http://japanesechefsknife.com/FKHSeries.html. It probably cost me $50.00 or less, shipping included. And, oh boy, although I watched so many sharpening videos in the past, I still managed to mess this knife in more then half a dozen ways; all because I was so eager. But, I knew my weakness and that's why I went for a cheap blade.
Start slow. Devote your attention, love and patience. You'll be ready for Yoshihiro sharpening challenge soon. In the meantime (according to your pictures) you have a plethora of Henkel's you can use. :wink:
