The Shrade extreme survival knife is a hollow grip fix blade knife. The knife is full tang, one solid piece of steel, unlike other hollow hilt knives which are welded to the hilt and of poor quality. The knife is pretty heavy, because of the solid steel construction, but it is a good weight for what you will likely be doing with the knife. It comes with a screw driver bit set in the hollow space but you can take that out and put whatever else you want in it. I put some matches for camping and a small sharpening rod. The grip is the only thing I do not like is the grip of the knife. The grip has many small metal beads all around it which feels fairly uncomfortable and abrasive, but you can easily wrap it in another material of your liking and have a much more comfortable grip, or just wear gloves. The sheath is good, but I replaced the shoelace style string with 550 cord and may end up replacing it later on with a leather sheath. The pommel of the knife is flat and good for pounding in tent stakes, but you can end up sliding off and causing yourself some injury if your not careful. It would be much better if they could make it textured like the waffle pattern of a hammer or something similar. The hollow spot in the hilt is water tight with the rubber O-Ring, but I would package certain things in a plastic bag just in case. The knife was hardly sharp when I took it out and I am not sure what the grade of the steel is because it is not stamped on the blade, but it was not too hard to sharpen the blade up after receiving it so it is probably a lower number.
