    Lee, in my humble opinion, that mold cutting jig of Gesswein's
    (other sell it too, I think), is kinda overkill, and frankly, I like
    my simple setup better.  I just screwed an ordinary 25 cent can
    opener to the flat portion of an extra bench pin (that fits my GRS
    bench pin holder).  The point on the can opener points away from the
    pin surface, which is mounted upside down in the holder, so the point
    is down.  The point projects about a half inch in front of the end
    of the wood.  It's sharp as sold, but i sharpened it a bit more. 
    it's easy to then use that hook to grab a bit of the mold and pull
    the portion of the mold on your side, away.  though you do have to
    hold the mold, I frankly like this better than that jig, because it's
    so fast to reposition the mold from one angle to another, and pull the
    rubber just where needed.  And my jig takes a lot less space to store
    than that complex one.  Plus it's really cheap and quick to make.
    Another comment, I let my molds cool to the point where they're not
    more than lukewarm, before I cut them.  I find that cutting the molds
    while still too hot leads to warpage of the rubber, and a mold that
    won't be as easy to keep shut when injecting.
