Yellow eBay 5 tonne lug crimpers as emergency shroud cutters?

Try using a shearing action on hard brittle materials

Try using the right tool or piece of equipment for the task

Would one also block off the fan so that the unit overheated? Or would one think that through & let soggy shrink wrap get in the works?
But with my £3500 I did the alternative & renewed my rigging.

Money well spent, but I doubt the necessity envisaged by the O.P. can be entirely prevented by renewing rigging in advance, however much self-assurance that brings; or that anybody looking for a wire-cutter intends being equipped to jettison their rig in preference to replacing it.

As Daverw remarks above, from cold, one could cut an awful lot of rigging wire with a grinder before it would overheat to the extent that it would stop cutting. To be fair I doubt many people in desperate circumstances would stop to cling-wrap a grinder, but not doing so would spell much quicker failure than overheating if it were actually immersed.

Interesting point. Might be worth practicing the wrap - or finding a waterproofing agent.

I would never use a tool with shearing action to cut glass of a ceramic tile

I would use a tile or glass cutter that does not use a shearing action like this below

This is a very different action than sawing where teeth on the saw blade remove chips out of the kerf using a sharp tooth to remove the chips (swarf )
