OK, I am the manufacturer/craftsman of the Hookshot. I didn't mention it on my first post because I hadn't gotten the rules from the site for manufacturers. Anyway I would like to address the health concerns about copper at high temps. I knew this was to be my biggest obstacle, but it's a misconception by the public. I of course have done a bit of research on the subject. I first looked all over the web (many hours) to find out about health hazards with heated copper, all I could find was MSDS's that state the fumes are hazardous "at extreme temps". Never did they give a temp. So I contacted a copper forger and they told me they work with copper at cold temps at 600 deg. F and hot temps at 1200 deg. F. They operate under OSHA regs and they are not required to use any ventilation or respirators. Finally, I asked support@welding-advisers.com the question "at what temperature does copper give off harmful fumes, at melting point or below, and if below, than at what temp?" They answered back "fumes are only released above melting temperature". The melting point of copper is 1981 deg. F, vaporizing temps are below 400 deg. F and a jet flame lighter cannot reach coppers melting temps. I have welded/melted copper and have seen the green smoke come from it, that's what you don't want to inhale.
Copper is a natural element essential to human life. IMO the only reason you don't see copper bowls/pipes is because it's second only to silver as a thermal conductor and would be too hot to hold. Ask away bout the Hookshot.
I have offered the staff here at FC a Hookshot to test and review. Flappa
