A wrecking bar is a sturdy tool used primarily for demolition and heavy lifting. It is typically made of steel and features a long, straight design with a pointed end on one side and a flat end on the other. The pointed end is useful for prying apart materials, while the flat end can be used to leverage and break apart structures like wood or concrete. This tool is often found in construction sites and is essential for workers who need to remove old buildings or clear debris. Using a wrecking bar requires some strength and technique, making it a favorite among contractors and handymen.
