Oh and file, grind or otherwise round the cut ends.
Nipping them to length leaves a wonderfully wicked corner that just wants to reach right out and slash the side of your thumb right down to the bone just when you have a monster size blob of hot molten glass on the other end with the master piece of a life time perfectly encased in a wonderful clear without a single air bubble in it.
I use the side of one of those disc cutters in my dremel tool and just rotate the point gently against the flat of the disk to round the end of the mandrel.
