I guarantee if you file your side edges and diamond stone them properly the hanging burr will be there. It will not break off when skiing because it is pointing down into the snow.
I have experienced numerous skis 1st hand that had not been deburred properly. And I have fixed them. I have also fixed numerous folks skis right on the hill. (I always carry a stone around with me)
if you want to ruin a day of skiing, don't knock the hanging burr off of your ski. It will make your skiing absoluely miserable.
You must remove the hanging burr with a hardstone after filing or diamond stoning. And yes you freehand the arkansas stone. The key is to simply hold the stone against the base edge with about 1/4 of the stone above the side edge, best done in a vise with the side edge up base facing away from you. Use your thumb as a guide along the sidewall (facing up in the vise) and simply with medium pressure, and polish back & forth.
Matching the stone to he edge angle is ridiculously simple. As long as you don't slip and roll the stone over the edge point (which is why you have a good amount ot the stone above the side edge)
My guess is that the reason mrzinwin is not experienceing this is he has way too much base bevel on bis skis or somehow is sharpening them incorrectly.
Read this article and Pay special attention to #8http://www.holmenkol.net/myadmin/datafiles/techimages/Prepping%20Your%20Skis.pdf

My older son ran in a USSA Masters race last Sunday on an extrememy hard and many described as very icy course.
He ran the fastest run of the day!!!! He also told everyone the run was a walk in the park and was not slippery or icy at all!
guess what, I tuned his skis!!!!! and deburred them!!
so you can go with mrzinwin, who went in a short few posts from asking how to properly use a diamnd stone to giving incoorect advice on tuning, or you can listen up and pay attention. I have been tuning constantly for over 10 years!!!!!
Eastern carver, a gummi is way to soft to use to knock the hanging burr off particualrly with the amount of pressure you msut apply to remove the curl of steel. And as I said because of the softness it hangs over the edge point when used in this manner.
But the 45 degree gummi stone treatment with absolutly no preesure as the last step, really makes a nice smooth edge.
Also do't discount usisng your arkansas stone as the last in the progression of stones to truly hone, sharpen and harden your side edge as stated in the article. This is after you diamond stone.
#8 in the article above is exactly how i tune our skis. Both my boys raced very seriusly from the time they were J5's until J1's Both qulaified for JO's numerous times and my older son had top 10 finsihes at Western Region JO's. And was the top PNSA racer in Sg and 2nd in GS. Again I tuned their skis.
My younger sons was ranked 4th in the country in Downhill as a 1st year J3.
they re now 21 & 24!
I have been thru an enourmous amount of trial and error over the last 15 years in technique and tools.
Good luck to your son this season. Those racing years we had together were the best!!
Can you deburr on the hill with a 600 grit diamond stone free handed..
