I currently use a kuromaku 1k, Goken Fuji 4k, Goken Fuji 8K, and an ILR 12-15K. Can I getter a different edge adding anything to the bunch, ie feel, looks, and possibly performance? I am not complaining about the wonderful edge I get off these stones but want to explore out of my safe zone but at the same time not breaking the bank on a $250+ JNAT.
