Stool... foam sit pad on a rock. Sit pad is also backpack pad.

Beer.... warm beer. Really?

Pillow... stuff sack stuffed with, um, stuff.

Saw... for what? Have fun making a fire with only a ferro rod. OK, you can cheat with PJCB (petroleum jelly cotton ball). But it's fun to find other stuff that works well, such as cattail fluff, birch bark, very dry beech leaves, etc.
