The Problem with Chandelier Light Bulbs

The holes are made in the tips of the chandelier light bulbs. Now, getting the filaments out of the interior is another story.  A online tutorial prompted the technique for carefully breaking the black tip to open up the end.

This worked fairly well initially, but the wrestling the filament became more of a problem because, although part of the filament could be broken and shaken out, the biggest part could not escape through the hole.

So now the question is what is a way to broaden the hole at the socket end of the bulb without cracking the glass or should the hourglass be made with the filaments left inside the bulbs?  Is there be a metaphor to explain the presence of the filaments in an hourglass, something about light and time?
