I only use panzer for initial 2 passes at 7 degrees depending upon the sidewall and ski. Then I sharpen with panzer at 1 degree more than my final angle. So if I want a 3 degree as the final angle, I will use the panzer at 4 degrees until edge is sharp.
then I switch files to a 100 mm 13 or 15 TPC no -chrome (Usually Homenkol) file at my final bevel angle of 3.
Then progression of stones, generally, 200, 400, 600 and then a final hone/polish with a surgical stone or ceramic all using 50/50 water/denatured alcohol mix and wiping down the edge with a rag between each stone.
Remove the hanging burr with an arkansas, surgical, ceramic or true hardstone and then a couple of NO pressure passes with a HARD gummi downthe edge point and you are ready to slice and dice!
