The SOG Jungle Safari has been a decent knife for a large blade. The length of the blade is 9.5 inches and is .15 inches thick. It feels much lighter than it looks. This blade has been useful but is a bit overpriced for what it does. A good solid machete will do most of the tasks that this knife is good for.
Lets look at what this blade is good at, it makes a very good chopper, the size lends itself to any task you would use a small machete for, clearing brush, chopping small trees and saplings and cutting high grass in areas around your camp. Last year at a bushcraft meetup I needed to clear out an area of hight grass to keep out the snakes and such and in a couple of minutes i was able to cut the grass in a very large area. The blade is light and swings well and you forget its on your belt very quickly. The pouch on the sheath is large enough to hold a full size multitool and when i am in the bush my Leatherman Wave usually rides in there. The sheath is tough and works well, it has a snap that holds the blade in place and the belt loop is very large, you can fit a USGI pistol belt in it with room to spare. The handle is very grippy and work well even when wet.
The steel is fairly soft and after a year of medium use it has a small warp in the edge of the blade, it holds and ok edge but sharpens easily. The saw on the back of the blade is better than nothing but is not something I enjoy using for any length of time. It is only a pull cut saw so it only works on the backstroke. The blade is full tang with a hammer on the base but it is a very thin hammer and is only so so for driving spikes and such.
The knife has done its job but for 40 dollars I would recommend getting a good machete or one of the versions of the knife that does not have the saw on the back of the blade as it destroys a baton fairly quickly and the saw is not very good. You can pick up a good folding saw, a machete and a small mora for about the same money as this knife and they would probably server you better. If you are limited to one tool this will do all the jobs, but like many jack of all trades it does none very well.
