Intital 2 passes at 1 degree over your final edge angle with a Panzer file. http://www.artechski.com/holmenkol-cross-file-mini-panzar-4-inch/
Then final side edge angle with a 13 TPC file http://www.artechski.com/holmenkol-crystal-finish-racing-file-4-inch-13tpcm/
There is also a 15 TPC File you can use as a 2nd cut file after the 13, .

And contrary to others, the ONLY time I use a 100 Grit Diamond is to smooth damaged ares on the edge.
You can diamond stone a newly filed edge starting at 200 then 400 (600 is optional)and then hone with a ceramic or I like a Surgical stone.
then remove hanging burr. the x-tra hard blue gummi with ZERO pressure down edge point at a 45.
Step 8 – setting the side edge angle – Now, you are ready to dive in to the steel. Most folks are running a 3 degree side edge angle today for all skis; some younger racers (J6 thru J4) may also be running a 2 degree side, which is OK, too. I like to make 1 or 2 passes with a 5 to 7 degree angle using a cross (panzer) file along the whole length of the edge; this allows the top corner of the steel to blend nicely with the sidewall. Next, begin sharpening your side edges using the cross (panzer) file and 1 degree more than you intend to run – use a 4 degree if you intend to finish with a 3. When you have a sharp ski from tip to tail, move to a mid or small sized file with the final angle you want, and continue sharpening. The process of finishing the side edge is designed to continually smooth out the previous work, leaving you with a nice smooth, grippy edge. I like to make a few passes with a middle grit diamond file next, of course attached to the file guide. This will really soften the rough effect that the file has left. I usually do this freehand, with light to medium pressure. Now you are ready to really put the edge on – use your Arkansas or ceramic stone with your file guide, and begin working the side edge steel back and forth until it is extremely smooth and sharp. At this point in a new ski prep, I will take an Arkansas or ceramic stone and lightly pass it along the base edge to cut the “curl” of steel that has developed from all this filing. A light pass on the edge point at a 45 degree angle with NO Pressure your gummi block will finish the edge off, and you should have a very sharp, smooth edge that is ready to ski.
