Abstract: A foldable, portable, magnetic tool mat. The tool mat includes generally rectangular obverse and reverse panels each formed of flexible material and connected together along substantially common side and end margins defining elongated magnet bar holding portions. A magnet is held within each holding portion each without substantially inhibiting selective tool mat folding for fit and storage. The reverse panel is substantially thicker than the obverse panel for better wear characteristics and maximal magnetic attractive forces for tool and hardware retention. An attaching strap can be used to hold the tool mat.
