I wouldn't support this because: the campaign project members are anonymous (and thus cannot be held accountable), the project is flexibly funded (meaning they get the money either way), and the key IS NOT A UNIVERSAL HANDCUFF KEY.<p>There was a presentation on "The Ultimate Handcuff Key" at CarolinaCon 6: <a href="http://www.youtube.com/watch?v=LjfGwRE_DF8&t=29m30s" rel="nofollow">http://www.youtube.com/watch?v=LjfGwRE_DF8&t=29m30s</a> where they demo and give data and measurements for all the handcuffs and keys they could find.
They show a calculated 'universal key', and how to make it. Notably it has a <i>notch</i> down the center of the blade.<p>Looking at the TIHK, they are very obviously NOT using this design.<p>You can, however, watch the talk and learn how to make one of these keys yourself with a specific handcuff key, a file, and a dremel tool.<p>Slides: <a href="http://deviating.net/lockpicking/slides/cuff_stuff.ppt" rel="nofollow">http://deviating.net/lockpicking/slides/cuff_stuff.ppt</a>
