Well, it turned out that I was taking EDC to ludicrous extremes.
Having pulled out the non-work stuff I found this pile - OK, one of the phones is a work phone.
Seventeen lights, a camera with 4 spare cells, two phones, an elderly ipod and seven multitools.
No wonder it weighed rather more than usual. And I doubt the need for 17 lights (on top of the three on my keychain, the one that lives in the filing cabinet and the extra one that lives in my desk.
Just a bit. Laptop, power supply, 3G modem/router and its PSU, paper, notebooks, pens, enough cables to anchor a ship, LiPo battery pack and adapters to charge just about anything. It comes to about 30kg in total.
I thought multitools were meant to allow for the convenience carrying less tools. I guess it could also mean that you're supposed to have multiples of them.
