A Windsor with two rounded safety edges, an 8" Grobet, a double round diamond hone and a 1/4" Grobet round. The Grobet regular is for getting them nearly razor sharp, the diamond hone gets the shaving edge, the Windsor with the rounded safety sides has the file teeth just sticking out far enough to add a fine serration to the beveled side. The round Grobet is for putting a drag edge on anything I want, Nate Sheen style, when I am using Hunter's Heads or standard Hills and am in a hurry. No matter what is said with long narrow heads, the serration has worked very well for us, but there is a difference between keen and rough. I also find that people new to sharpening with a file have better luck when file sharpening Zwicky Eskimos.
