I had written this up for my own records, this is always a work in progress. I thought it would fit well in this thread. Mac
Becker BK-7 Kit
Specifications and Reasoning
The knife kit presupposes the loss of all other gear. The very idea of a survival kit located on the sheath knife is that the knife is the most basic piece of gear and stays belted on during any wilderness activity. It cannot fall out of a pocket and is unlikely to be left behind by accident. It is unlikely to be lost overboard or swept away when crossing a river. If a person needs to exit a burning vehicle the kit goes with him while the pack may be lost.
Placing survival items on a knife sheath also presupposes that the normal items carried in the pack cover any foreseeable needs and that nothing in the knife kit should have to be used under normal circumstances, other than the knife itself. They are limited to the items necessary to spend a night or two in the wilderness and signal for help with no other resources other than the contents of the knife kit. The items in the kit must be capable of getting wet and must not degrade with time.
The other item that should be belted on at all times is a US Army canteen with steel cup and stove sleeve. The pouch on the canteen carries two bottles of Potable Agua, a mini-bic lighter, and a small foil packet of KMnO4 as a back up water purification system.
HANDLE CONTENTS – The handle scales of the knife can be removed to reveal two small hollow cavities. These are removed with a small hex-wrench and filled with a fishing/trapping kit: line, sinkers, hooks, wire.
SHEATH CONTENTS – The sheath has a pouch that fits an Altoids tin and there is room below it to attach items with a rubber sleeve. Paracord is attached to the leg tie at bottom of the sheath and the wrist lanyard hole on the handle of the knife.

SHELTER – The shelter provisions are intended to make the construction of an expedient shelter easier, not necessarily to compose a shelter. There are three components, water/wind proofing, heat proofing, and cordage. In practicality only a space blanket will fit on the sheath, attached by ranger bands below the pouch. The space blanket is waterproof/windproof and will trap body heat. The duct tape is used to seal leaks and join seams. The space blanket and rolled water carrier is no more bulky than the pouch and Altoids tin above them.

Yep, for sure Swamp Rats knives are great, and might be stronger in extreme tests conditions, but I'm pretty sure that a BK&T will do the job in any given human condition. I know plenty of Marines who made it trough exteme hardcore stuff with their Ka-Bar! so not to comand anybody,but just to suggest,if you only have a BK7, don't feel under-equiped, and instead of getting a Camp Tramp, invest in some cool survival gear.
