I have been learning to hone for the past year now and use Nani's 1,3,5,8 & 12k's. Very happy with my edges but would like to move to the next step or level. I have read a little about the Suehiro 20k and it seems to be a good option for a synthetic person. No idea of where these are available and am interested in suggestions as to where to go from here. Other options for that next level. I am very picky/critical about my edges. When I googled Suehiro 20k I only got one eBay hit for purchase and I'm not too enthused about eBay.

Thanks.
