I was thinking about that Q yesterday, when working in the garden.
I carried a combo of the Frey and the Odin working with chopping and slicing weed, 2" Ash and some carpenting.
The Odin shines in chopping, without being too bulky and it cuts very well too!
The Frey was used for smaller jobs.
It is thinner for good cutting performance and it processed weed and wood with great accuracy!
The Frey is too small for chopping and the Odin is my choice for this.
I know many NL users prefer the Njord, but I think it's too big for small jobs and too small for big jobs.
Out of these 3, the Frey, the Njord and the Odin, the Odin was my first choice.
It still is and for a do it all Cross-Over knife, it's great!
Nowadays when I'm in the outdoors, I carry a smaller fixed and if I also take a big knife, it is in the daypack.
The big knife would be enough, but if I get spectators, I don't wan't the attention a big knife gives and I take the smaller one instead.
Another thing, why invest in such expensive knives as the NL's, when the market is flooded with less costly alternatives?
The answer is that this will show on more extended stays in the Outdoors!
For a few days camping in the nearby forrests, they are overkill, but when the going gets tougher, they start to work!
I don't do those tough Outdoor stays, but I enjoy the high quality in fit&finish and the feeling of a tool in hand that I can depend upon.
I guess You want me to say that You should choose the Njord over the Frey.
I say the Odin, but among many others my son prefers the FK 6" blades. instead of the 8" versions.
So if 6 to 7" bladelenght is what You are comfortable with, ok then the Njord is the right choice!
