Hey Horus....
you've picked two Great knives....
However..
You've picked two completely different Beasties...
The Fallkniven is a heavy duty outdoors knives, which will do Anything you want it to, however it's not big on being a fighter..
The Nimravus is a good all around every day type of knife that isn't suited for heavy outdoors type work....
As far as looking for a knife for self defence,, the Fallkniven will definately do the job for you,, just not as well as the Nim will...
The Nimravus would be a better choice for self defence..It's light quick and thin enough for slicing and defence type duties...
However if you plan on carrying the Nim concealed the sheath isn't well suited for this type of carry...The sheath is Definately the weakest part of the Nimravus....
