The fellow in the video uses simple duct tape to contain his shavings. As Erin pointed out a few weeks ago on the Gunblog Varietycast, one of the many neat features of duct tape is that it burns quite handily. Combined with the magnesium shavings it makes an excellent, if unexpected, firestarter. It also allows you to shave your magnesium at home, where you can a tool that is far more efficient and faster than your striker.
I'll attach the video below, but for those of you who can't watch it for some reason, here is the summary.
- Using whatever tool is easiest, make a nice pile of shavings. The example from the video is a file, but there are a number of other tools that would work. Having a sheet of paper or plastic to catch your shavings keeps everything contained and under control.
- When you have a decent pile of shavings, take a square of duct tape, roughly 2" by 2", and rub the adhesive side in the shavings until it is nicely covered.
- Roll the tape into a cigarette shape, adhesive side in. Roll it at a slight angle, so that when you're finished, a tag of adhesive and shavings are visible on one end of the cylinder.
- Store in a plastic bag or some other water-tight container.
