So I was thinking of a safe, but effective way to trip to mine.
If you used magnets; One on the inside of the claymore and one attached to the end of your trip wire.
Reason being, magnets can be pulled apart easily enough to not cause people to actually trip over the wire. And they can be pulled apart in any direction.
The inside magnet could trip the mouse traps when the outer one trips causing them both to fall.
Just a suggestion though
Not a half bad idea, though there's no really easy way to make a magnet trigger the device.
