haven't tried, but read a sponsor does well on them http://www.fish307.com/
They are awesome and they do an exchange as well so you don't have to wait as long for your blades.
I read a couple of seasons back about using a dremel tool with a polishing burr on it with polishing compound. Only polish the top of the blade and make sure the tool is turning "up" from the edge and not into it. I have honed sets of blades for my mora this way with great results...only way I ever had any success.
