: You can also play with the edges, some folks have experimented with having
: one edge very sharp and the other more blunt, but I haven't heard any
: solid results. Of course during sculling and other techniques, the leading
: edge changes, and this may cause handling problems. I generally prefer a
: symmetric paddle, it will act more neutral in rough conditions, and will
: roll and scull easily without any surprises.

Both edges are the same, and just sharp enough to be comfortably gripped. Only the center of the blade is flatter on one side. Sculling and rolling are Ok with both sides, the difference is marked only in the forward stroke. Looking at the blade the difference is not dramatic.

I was really surprised that the difference was there for the forward stroke, but that no problems appeared with other strokes.
