: I would think it would cause the blade to be more stable (less tendancy to
: flutter), but might cause problems in bracing and rolling?

Greenland paddles with a roughly diamond cross-section have dihedral on both faces, and are reportedly very easy to roll with.

Too much dihedral that is reflected in the back face, though, can make your paddle dive when you're low bracing.

The theory behind dihedrals is that the water vortexes will be split at the dihedral and spill evenly off of both edges. Otherwise, they traveling back and forth across the paddle face, spilling more off one side, then the other, causing fluttering.

If you can create a paddle blade that has decent thickness in the middle (thin at the tips, though), you get more buoyancy, less tendency to dive, and easier rolling and bracing.

: I squared the block on three sides, set the bandsaw to make an even cut, and
: have blades of uniform thickness across their width, but obviously went
: wrong (or right?) somewhere.

: Compensating at the shaft as Nick suggested would be easy.
