Hey Rat, the first one you have linked to looks solid to me. Notice how you can see that the metal is round and pretty thick, I think it is basically the same as the one I have. Also it looks like it has been properly bent into a re curve ish shape. On mine I redid the paracord wrap as I did not like the way they had done it. Also I found the bands useless as the came too short. Remade them into pesudotapers and they work a lot better. Mine did not come with the pouch / holster so I am curious as to how well those work myself.
I also had one like in the second link and literally tore it apart with my bare hands no gloves needed.
