Reddit mentions of Kershaw Knives Folding Saw, Santoprene Handle

ESEE-4
Sturdy, perfect length, perfect thickness for batoning, easy to sharpen (1095 high carbon steel, has never rusted even though I live near the coast).
I recently found this knife, it's very cheap and it's metal composition is very similar to that of the ESEE-4 (1095 vs 1075), except that it has less carbon which means that it might be negligibly harder to sharpen but just like the ESEE-4 both are knives very resistant to chipping and this is an excellent quality for a knife that will be used for batoning. What I like about the Condor Sapien is that it is a little bit thinner and the scandi edge that comes with it makes it easier working with wood since that type of edge offers less resistance when cutting stuff.

Fallkniven knives are nice but rather overpriced and I am not such a big fan of laminated knives and stainless steels are usually prone to chipping and hard to sharpen if you use them often and don't give them their proper maintenance.

In my opinion you would be better off with a folding saw or a small axe, a bushcraft knife, and a multitool, the perfect triad.
