Inexpensive survival knife
by G.Gelbart
(Montreal, Canada)
Get a large "saws-all" coarse-toothed metal cutting blade. Sharpen the 'back' edge and put a few layers of tape on the end for a handle. You could also shape the little projection at the end into a screwdriver.
These blades are hard tool steel, will take and hold a keen edge. Make a sheath for it and you're done.
Learn to survive in the wilderness.
