I used alot of time finding reviews and info on this knife when I was looking for something new, but there was always something wrong,IMHO, with this knife: 1) I think that the holes for making the knife into a spear are just a gimmik, if you are planning on doing this then you shouldn't be outdoors in the first place, 2) the "skull crusher" pommel may work on helicopter windows but I don't see myself being in that situation and 3)the sharpener I feel is also a gimmik. The positive things about the knife are the double snaps and that the sheath holds the knife, all of this to make sure that you don't loose it.
In the end I bought a Fällkniven A1 and I am VERY pleased with it. I was expensive but I wanted something that i could beat up and would work and it does everything I ask of it and more!
Good luck hunting for your knife.
