Thanks so much to all who took the time to advise me on this. If I opt for the Edgepro, it'll definitely be the Edgepro essential -- http://www.chefknivestogo.com/edproesset.html
-- so no need to discuss that further. The strop set is likewise pretty uncontroversial. I'll be getting that for sure no matter what.
On the stones, if I want to do it on the cheap, it seems I can get by
for now with my King 1K. Yes, there are better out there, but the King in the hands of a competent freehander will put a serviceable 1K edge on every knife on my list if I understand the consensus.
For my nicer knives I'm going to want something higher than a 1K edge, and many say the RIka 5K can be used directly after a 1K with no difficulty. Certainly a lot of you recommended it. But I've read good things about the Arashiyama 6K, too -- http://www.chefknivestogo.com/takenoko8000.html
So, if you guys had to add just one stone to a King 1K, would it be the Rika 5K or the Arashiyama 6K, and why?
I'm pretty sure I will eventually end up with the 400 Latte and the Green Brick, too, but that'll be down the road a ways.
Thanks in advance for any answers.
