I'm really wanting an RC-5 still but I don't know if it's worth it since I don't really camp/hike often so I don't know if a "serious" knife is absolutely necessary.
All of the knives you're looking at are "serious" in one way or another.
The RC-5 is a great choice. A very useful blade length for many tasks,
super build quality, and pretty easily saleable if you change your mind.
The Fallkniven S1 is similarly sized, similarly priced, and also a great blade.
If I had to choose between those two I'd personally pick the Fallkniven, but as for
quality and overall usefulness it's pretty much a coin toss.
The Fallkniven S1 is one of my favorite fixed blades. It doesn't look like much in pictures, but it's a heck of a thick piece of laminated VG-10 stainless that can take an awesome beating and still function well.
The RC-5 sheath offers more carry options, however.

As for the info from the Boker website on place of manufacture, I'm sorry to say it's inaccurate.
I have held some models of the Boker Plus Chad Los Banos ("CLB") knives in my hand and have seen the "China" label on them.
(But some models of the CLB knives are, in fact, made in Taiwan.)
