What is a "non-sparking" tool? "Non-sparking", "spark reduced"
"spark-resistant" or "sparkproof" tools are names given to tools made of metals such as brass,
bronze,
Monel metal (copper-nickel alloy), copper-aluminum alloys (aluminum bronze),
or copper-beryllium alloys (beryllium bronze).
Commonly used hand tools are often manufactured of steel alloys.
Preferred "non-sparking" metals have less tensile strength than steels usually used to make tools.
