As part of my "Try to write more blog content" We are going to look for a backpack/camping saw.
Must be around $15-$20 max.
Must be suitable for sawing branches around arm thickness.
Space/weight considerations are paramount. This is to help gather firewood as part of a bailout bag/BOB. So carrying around a chainsaw or an ax is not going to happen.
From reserch I've done we are looking at the following.
A notched wire between two rings.
Probably way too light. Suitable for only kits that need to fit in a mint tin.
Survival saw, chainsaw:
Looks like a chainsaw chain between two handles/straps
Folding camping saw:
A saw blade that folds like a lockback knife
Folding frame saw:
Saw blade in a folding frame
About the biggest I'm thinking for this purpose.
Also likely the most useful for cutting wood in quantity.
