These hooks are incredible and we have the people at Boss Tin to thank for them. Molded Tin - Bismuth alloy on the Tiemco 2457, this hook is heavy and built to last.
The specific gravity of lead is 11.35 and sinks like a rock. The only problem is lead is toxic to humans, waterfowl and fish. The Tin - Bismuth alloy has a specific gravity of 9.79. That's as close to lead as you can get!!
These hooks will eliminate the need for lead wire or flat lead wraps required to achieve the weight for tying Czech nymphs and are super easy to tie on. Specifications:
