I just got my Naniwa Chosera from Mark at http://www.chefknivestogo.com and WOW! I love this stone, GS are great stones but again WOW, there is a huge difference in the time you spend setting a bevel, and in the feed back that you get from this stone. It is the best 1k I've tried. Easily beats out GS, Norton, and King. BTW, Mark has the best price on these stones at $76.90 with free shipping and great service.
