I use a brain tanned chunk of thick coyote hide and strope it off the belt of my buckskins. Just kidding, I tried brain tanning once--the hide never tanned and got to stinking--but I digress. I use a little ceramic pocket stone. I just keep it clean with water between uses.
I use a ceramic rod too. I just spit on it and rub it on my jeans to get the metallic build up off.
