Good info..... I think my edge file tool is a 88*/90*.
With my BG I use the 88* on the side and the 90* on the base.
Wrong or right?
At this point my edges have huge chunks missing from riding, so I'm headed to the board shop soon.
A bunch of the basic edge tools that you see in shops (like the Dakine one, but they are all identical/from the same China supplier) offer 90 degrees and 88 degrees only.
IIRC, the BG is 0 degree base and and 90/0 degree side], so if you have gone 88/2 on the sides you have really sharpened the edge.
My recommendation/what I did with mine:
- I would not do anything to the base of the edge, other than occasional removing burrs with a stone (and fix any major nicks).
- Use the 90/0 setting for the side edge.
Worked for me.
