Yes the edge pro works great on most knives including the konosukes.
If you're concerned about patina I would recommend you get the HH instead of the HD. The difference in performance is almost nil and the HH are fully stainless. http://www.chefknivestogo.com/ko24wa.html
It's a great knife and I think you'll really enjoy using it. It's quite a shock to pick it up after using German stuff since it's so much lighter and the difference in cutting is pronounced. You'll be impressed I'm sure.
