So your illustration is indicating that your base edge is zero degrees, flush with the bottom of the board correct?
In my experience a zero degree, dead flat base edge grabs really quick for obvious reasons. The side angle is difficult to estimate from your drawing especially when dealing with increments of 1 degree. But it could be a side bevel of only half a degree or a full degree. A lot of bordercross guys ride 90/89.5 or 90/89.
But the grabbiness on your finger could be caused by factors other than your edge angles. The steel quality of the edge can impact that and how recently it was sharpened.
