Frequent and prolonged jackhammer use can turn a laborer's fingers white and numb. The vibrations damage nerves and cause the small blood vessels in the hands to spasm, inhibiting blood flow to the digits until — after years of trauma — it stops altogether. That's why the $4,290 Wacker BH24 breaker is designed to be gentle on its master while busting the crap out of hard things like parking lots and basement floors. This 57-pound demolition machine tops its class in smash, delivering 1,250 blows per minute measuring 65 joules each. To reduce the shudder to the operator's body, the gas-powered hammer uses a spring-mounted hood and a rocker bar to absorb about a third of the shock force running from the steel chisel to the handles. Less shake means users can pound for longer periods before their hands fall off. A-w-w-w-w-some!
