A couple years ago I bought a used Old Town canoe, and then needed paddles of course. I knew just where to go.
Shaw and Tenney has been making canoe paddles in Maine since 1858. Their shop is in Orono, just down the street from where I lived for 3 years, on the banks of the Penobscot River. They make beautiful paddles.
I went right to the store in person and bought paddles that were seconds, that had some tiny flaw and therefore were discounted in price. The paddles are not cheap but you are getting a handcrafted product that will last a lifetime. My friend Sam makes them himself, in fact.
Here we are putting the Shaw and Tenney paddles to use at Little Falls on the St. Croix River last summer:
