My first thought was "New bike lock material"

My second was:

"New non-cuttable bike lock defeated by ______"

{freezing, shock, heat, _ }

[omgtehlion]

"... a tool bosnianbill and I made."

[mparlane]

More likely it will be picked rather than cut at that point.

Luckily for us, most people who are very good at lock picking (or good at learning new skills) can find better work that becoming a bike thief. Making bikes harder to steal results in fewer stolen bikes.

This says nothing about the momentum of the cutting tool. My immediate instinct is: "New non-cuttable bike lock defeated by - Cable Cutters - "

Great engineering regardless, would love to work on a project like this.
