Here are some screenshots of my "bolo" knife made by some blacksmiths in a nearby village. They salvage metal from everything you can imagine to make knives/bolos/whatever. The most commonly used metal, like the bolo below, is made from old leaf springs from cars/jeeps. The real good metal was from old Willy jeeps, but that is hard to find now.
The blade is ~30cm (just under 12in.), and weighs around 600 grams (~1.3 pounds) without the case, and the thickest part of the blade width is just under 1/4 inch. The woven wrap on the handle and case is from rattan. This is considered a smaller version.
Typical "minimal" survival is a bolo, an old empty 6 liter plastic water container (carried around empty, but used as a water container for the camp site), a water bottle for use while traveling, a lighter or matches, and an aluminum pot with lid for cooking rice/beans/meat (salted/smoked). I prefer to bring a blanket because it can get cold at night, but the locals just sleep where they lay, as is. There are a couple more things like a hat and sunglasses because it can be very bright and hot in the day. For shoes: wear sandals =D
Edit: The blunt edge is sharp, and excellent for taking the skin/bark off of pine trees to make firewood. It makes it easier for your muscles to change position of the blade if you get tired.
