You need to relax. Don't fight!

Just leave your survival kit in whatever pouch it is and start carrying a small kettle or metal cup, on the side. Sometimes, there is no perfect answer.

This is what i've been doing for a while, and it works... not that I was involved in a survival situation, but hey. I am using a Primus LITECH hard anodized aluminium kettle and it works perfectly over a fire or on a stove.
