I contacted Forum and they said there is a 3 degree bevel on the Destroyer and on all of Forum's park/jib boards.
That's a pretty intense bevel. I am quite surprised. My geuss is they also have a 87 degree side bevel. So you can either leave the edges alone to maintain the 90 degree corner, or buy a 88 or 90 degree side sharpener and round off the edges slightly for a more forgiving edge.
