I ASSUME THIS IS MY PADDLE
I assume the paddle you have is a black carbon fiber Werner paddle (Player model specifically, but it wont show on the paddle). The shaft is straight as well. Paddle should look worn considering it was my first paddle 8 years ago. There should be a micro tear on the left blade on the bottom side of the face, closest to the shaft...(very minor tear)
I had made a post a month back and honestly gave up on it. It wouldn't surprise me that you found it at the undercut considering i let go of the paddle during hydraulic 2 in Rigo.
