Base edge bevel

[Monty]

The [base edge bevel] is the degree of upward ski or snowboard edge angle away from the snow surface.
[Base edge bevel] allows the ski or snowboard to skid at the beginning of the turn, prior to hooking-up or engaging a turn. The result is that the ski or snowboard is less likely to get caught-up on the snow and throw the rider into the woods.
Too much base edge bevel can result in skidding a turn or not having enough [edge hold] on the firm, hard snow surfaces resulting in a yard sale.
