Imagine having to do the work of a jackhammer using a sledgehammer or a pickaxe, and you'll quickly understand how important this one machine is to the construction industry. Concrete, asphalt and rock are hard -- sometimes really hard -- to work with. Thanks to that toughness, roads and building foundations last for decades. But when rebuilding or mining projects require removing these unyielding substances, a sledgehammer just isn't enough. That's when jackhammers come in handy. T-shaped jackhammers are among the most iconic, fearsome and ear-shattering tools on construction and demolition sites. Because they combine two fundamental human hand tools (a hammer and a chisel) in one mechanized body, they are also one of the most useful. We could always go back to the old way -- using heavy-headed sledgehammers -- but there probably aren't enough chiropractors in the world to keep construction workers' backs aligned. Plus, sledgehammers are achingly slow.
