The setup is slightly angly, and the handling showed in the trailers isn't shown in the DVD, but
wouldn't be difficult to figure out. I was under the impression that the trick used a double edge
blade, but it uses a single edged. Dvd is about 38 minutes long. Also, it says 'no stooges' but
the only performance that shows a spectator tying the knot, it's the same guy he taught the trick
to. In addition, the guy being taught is who's work you get to see, not the guy actually teaching
the trick.
