The AMPCO 7920 German-type sledge hammer will run you $900 on Amazon. Believe it or not, this 23.79 pound — when you pay almost $40 a pound you want to be accurate — German-type sledge serves a practical purpose. Its non-sparking, non-magnetic, corrosion-resistant, beryllium free head meets OSHA and NFPA requirements for use in hazardous, flammable, or combustible environment. So you can break s#!$ just about anywhere.
If that isn’t enough to make you run out and buy one right now, AMPCO’s offers a lifetime warranty. (They don’t specify whether that lifetime is the tools or yours, though. We hear toxic waste can sting.)
Don’t forget to read the reviews on Amazon as you rush to purchase this sledge — they’re quite amusing.
