Field shovels are the only way to go. Hell, I even fixed my jammed G3 with my shovel.
Atleast the variant we use, it's an combo of shovel, hammer, axe, pickaxe and knife, it's not really good at anything, but it get's the job done for everything.
As for knife, get a Sami knife or some rambo shit that is sharp, heavy and strong, small knives are useless as steppen said...
As for tent, I'd rather buy a proper sleepingbag, one that is light, water resistant and warm. And maybe a "Jervenduk" (mountain cloth?D:!), they are fucking awesome and light. As for bagging girls, build improved shelter, makes hoés think you are manly and strong.
