Pros: Weight, Overall Quality, Materials
Cons: Blade Sharpness
Neat survival item, and a great gift for knife lovers
This is NOT the only thing you'll need to save your life, but it's the best gadget to spread around so that you're never without some sort of blade in an emergency. Breaking away the scored pieces gives a reasonably sharp, but not very durable edge. However, as a safety feature, it will bend under pressure, and not shatter like a double-edged razor. A self-inflicted slash is the last extra thing you need in an emergency. The cutting edges can be restored a bit by stropping on a piece of leather as you go along. It's innovative and inexpensive, and infinitely better than having no blade at all. I have them stashed in my wallet, first aid kit, tool kit, and magazine pouch. Gadget lovers will find other places, and the gee-whiz factor is extremely high, making it a perfect gift, too.
