If you're looking for a large survival knife, the Jungle Canopy deserves serious consideration. At 1lb 9.625oz, it's definitely not a light blade, but if you can take the weight, this is a seriously versatile large trail/camp knife. It is much more versatile than an axe or hatchet, and safer to use as well. It also allows much more fine control than an axe, which can be critical in fire building, especially in extremely cold conditions. The knife has a good amount of heft, making it a good chopper, and it batons through logs like butter. The blade is made from 8Cr13Mov steel, and is fairly strong and rust resistant, although as with any steel, maintenance will extend your service life. It is also fairly thick at a full 1/4", and will stand up to a lot of abuse. There is a bit of gimping on the forward portion of the spine of the blade, more than likely for traction when using the blade for pull carving. The kraton handle is very comfortable in hand, and the hook-shapes swell at the far end aids in gripping toward the end of the blade, increasing your leverage for a heavier chop. The three holes through the handle allow for either lanyard attachment or lashing the knife to a pole for an effective makeshift spear. There is also a hammer pommel that can be used with a fire starter, or as a glass breaker in a pinch. Add in the quality of the SOG name, and you'd be foolish not to consider this knife in your search for a large survival blade.
