What has caused the significant reduction in weight for modern survival kits?
Answer
Advances in material science for packaging and steel
Comparing 1950s aviation kits to modern equivalents reveals a dramatic difference in weight and bulk for the same duration of survival. This change is primarily driven by improvements in material science. Modern components, ranging from high-performance plastic packaging to advanced, lightweight blade steels and ferrocerium fire-starting rods, allow for the same functionality as older gear but with far less burden on the user. This iterative process of refinement has made high-quality survival gear much more accessible and portable for the average civilian.
