I was shown to use a thin diamond file to score and break the filati into the tiny size pieces you want. Since using it more, I tend to lie the filato on my work bench and mark along the length of the glass stick the intervals I want to cut it to. If you are working in a shallow bezel you can cut it smaller, or in a thick bezel leave it a bit longer, or keep it all short and just use more Apoxie Sculpt to raise your height....
......anyway, I use a thin black Sharpie and mark all the way down like the increments on a ruler... then I get my sharpest wheeled nippers, and ones where the wheels touch almost when you use them. Then I just sit there with a tray on my lap and my hands comfortable, shoulders relaxed and feed the stick into the wheeled nippers and gently cut the tiny pieces, collecting them in the tray. I find especially when working with the 1 and 2 mm sizes I have less breakages and more straight cuts using this method.
Choose the method that works best for you.
