Cameron - The tinsel is one layer only. Started at the butt ad wound forward. It is Lagartun wide metal tinsel.
The hook is from an unknown maker. A fellow at my tying club stumbled onto a batch of blind hooks of various sizes and styles a while back, and I bought them at a very reasonable price and have put a few to use. That one is a 5/0 and reminds me somewhat of a Ronn Lucas, Sr. Phillips-Jones model. The finish has seen better days, hence its position on the magnet. I plan to work on it a bit to try and rehab it.
