I just finished my latest paddle. It's a modified ottertail with carbon fiber laminated blade. The 5.7 oz carbon cloth allows for just enough flex in the blade that should reduce impact on joints. The core material is cedar with a 1/4" strip of ash running the length to give it some rigidity. As with all my paddles the edges of the blade are very fine for silent paddling. It weighs 470 grams.
Here's a close up of my bear logo and the great 3D effect that the twill weave gives.
