More and more people are talking about civil war, or at least civil unrest in Europe and the UK. One weapon I consider very useful, which won’t physically harm the enemy / aggressor is a very high lumen LED torch. This temporarily blinds your attacker, for up to 30 minutes.
This will enable you to easily retaliate. Available on Amazon (large selection) some are military grade. Prices start from £2.57, Yes that’s right, a paltry £2.57.
I bought three which are 10,000 lumens. The other great thing is, because they’re LED technology, the batteries last much longer than a conventional torch. Size?? About the length of the palm of your hand by a 3cm diameter. Fantastic bit of kit.
