Norm;
I have carved about 100. My first paddle was carved from a 2x8 picked up at a construction site. I got into laminating; for strength, weight containment and contrast/decorative, then went back to more traditional solid wood. I have also experimented with a variety of end/tip protective treatments (fibreglass sheath, transverse spline, epoxy).
It's a "labour of love". I call it, "supporting my habit".
Many are gifts. Sales tend to be charitable (eg. WCHA Assembly auction, YMCA) and
special interest/ceremonial; wedding and retirement presents, commemorative (events), etc.
Here in Ontario, the market is saturated with paddle-makers.
Several companies seem to have come and gone for a variety of reasons.

Murat has done a lot of research into historical paddle designs and decoration.
He used to have a "rolling" photo archive of his paddles, but I am not sure how to view that.
