i have a 09/10 stepchild jp walker, i watched some guides on how to detune your edges so i did with just a regular file. last season i had a used board with old dull edges so i didnt catch on my boardslides but how far do i de-tune? do i just take off the razor sharp edge which i already did or litterally round off the edges?
