I have the main Esee lineup minus the lite-machete and Izula 2 , and Fallknivens F1,S1 , and A1. Totally different knives of course , but I would put as much faith in a FK as I would an Esee blade.
Fallknivens are almost maintenance free , except for cleaning and sharpening.
They can handle a lot of abuse , but their fine convex edge does need a little more respect as far as hitting hard stuff with it. Once you sharpen them a few times , the edge gets even more tougher. I bet you most of these guys who micro-chipped their edges never sharpened the thing from what the factory edge is. My favorite size is the S1. It has the clip point which I like better than the drop point of the F1. The A1 is a heavy knife; kinda like carrying the Esee 5 around with you. But , it can do a heck of a lot of bush work.
I never worry too much about rust , but then again , I'm not dumb enough to leave my knife lying around wet too long but with FK's , you can and not worry about it at all. Strange I don't see any posts of guys using them in the Jungle , as it's a very corrosive environment and the Lam VG-10 would hold up really well along with the Thermorun handles/kydex sheath set-up.
