I use stones on scandi grind blades because I can lay the grind on the stone and know it is perfect.
Every other grind goes on the Lansky or the Gatco.
I also find that knives with steel like what is used on Russell Green Rivers can be sharpened on about anything. More exotic steels and those with Rockwell numbers in the 58 and up range come out better for me on a guided system.
