Science and Tech Conjecture: Metal Foam Axe


This conjecture was largely inspired by my research into metallic foams and the clear need for more advanced designs in firefighting tools and equipment. This design would take advantage of the amazing material properties of this foam to create the fire axe of the future. Wooden handles break but a single piece steel foam construction would be nearly indestructible and weight would negligible as metallic foam has the same strength as homogenous steel at half the weight. This type of construction would also allow for ideal distribution of weight to keep overall tool weight down, while maximizing strength and impact. In this conjecture I added inserts of different materials that would be cast into the foam, tool steel for a solid and strong blade, and ultra high density steel alloy for added localized impact.
