The Bernzomatic Lawn and Garden Torch is specifically designed for outdoor use, and can burn weeds away in hard to reach areas such as the cracks of your driveway, cement patio or between pavers. The torch should be used outside on non-flammable surfaces such as brick patios, or concrete or gravel driveways that are free from debris, and it can also be used to light bonfires. The Bernzomatic Lawn and Garden torch runs on a standard 16.4 oz. propane camping cylinder. In addition to weeding and lighting campfires, it is also a tool for minor asphalt driveway repair.
