noo, i am pretty sure they are pre-grinded at the factory.  if you look at the bottom of this first paragraph it says factory rounded... meaning they grinded them down.  not angled them.
This is T-Hall's first signature model. Designed with a job-focused goal in mind, T wanted his ski to have the same sidecut and basic construction as the proven AR5, but wanted to change the flex pattern to help take his skiing to the next level. Tanner's own flex pattern is stiffer under boot for stability with softer flexing points in the tip and tail for nose and tail presses, butters, and whatever else he wants to do. He also wanted the factory to round his edges under boot so he won't catch and stay smooth on rails.
Terrain: Park, Urban
Features: Edges that are rounded under boot, T-Hall's jib flex pattern
Construction: AR Core torsion box construction, ABS Sidewalls, Carbon Fiber Stringer, 2000 Base, new nylon top sheet.
