I wonder how long it would take before it would actually cut its way completely through?
It reminds me of a MythBusters episode where they tested whether you could cut through jail cell bars with dental floss. They rigged up a machine that pulled a loop of floss around the bar for a few days. It did cut through a minuscule amount--almost just an etching really. Their estimate of actually cutting through was something insane like a year of 24/7 cutting.
