Sven Saw

Sure, it’s not quite as small as the pocket chainsaw, but the more versatile Sven is a bow saw that packs safely into its handle for easy transport and weighs in at 16 oz. Perfect for felling trees or making firewood while backpacking, though carrying one in your glove compartment/day pack/anywhere else it would fit might not be such a bad idea, what with the impending zombie apocalypse and all.

Get the 15″ at WoodAndMetal (30$), or at Amazon in either 15″ (30$) or 21″ (35$) varieties.
