I am a beginner to fly tying. I got several fly tying tools, vise and materials from a friend of mine years ago. They have been stored for years and I have decided to start tying flies, since I am retired now. The guy tied hundreds of flies for a fishing club. He mainly tied flies that used lead wire on the hook to sink these flies. I am concerned about the years of him using lead wire with his fingers and touching the vise and all of these tools. I don’t want to get lead contamination by handling these tools. It might seem silly, but I am concerned about lead exposure. Let me know your thoughts.
