Graham Warren refers to this design more precisely as a "North West Voyageur" simply because it appears in the voyageur art of Howard Sivertson. For some examples, I checked out a book of his entitled, The Illustrated Voyageur: Paintings and Companion Stories which has some delightful anecdotes and illustrations, although probably not entirely accurate.

Unfinished paddle; Blade Closeup
Since I was using left over cutoff scraps, the grain pattern isn't perfectly symmetrical on the blade. There's also point on the blade where the grain reverses suddenly giving the appearance of a horizontal "scratch".
I've read plenty of criticisms of this blade design on canoeing forums with many paddlers literally calling this blade shape a piece of junk. Personally I found it an acceptable design although the larger squarish tip certainly made for a noisy entry and the recurved shoulders tended to cause some cavitation and loss of power when paddling with a quick pace. But I found that if I slowed down and relaxed the pace it handled well with underwater recoveries. The walnut-poplar lamination also resulted in a super-light paddle and there's no denying the rich-chocolatey appeal of the wood. Instead of adding any additional pyrography to this one, I've settled on simply oiling it and using it as an occasional light use paddle
Final work all oiled up
