>>2062646thank you for making me understand what bothered me about them. I always saw them presented as the bee's knees in hiking videos, but something bothered me about a cooking ustensil with a small surface and high walls, never put 2 and 2 together that there were designed for already hot/cooked food to be laddled into it, not to cook with.
I have and old school 3 piece rectangle military canteen that has all the same advantages listed by
