L & H Fire Heated Branding Irons are made of rust resistant non-corrosive, heat resistant copper alloy and have a 1/4" flat face. They produce a good clear brand because the unit is vented at intersecting points to prevent blotching. They are also equipped with a heavy-duty, one-half inch steel handle, thirty-two inches long. These branders will not turn ash grey as steel irons, but will retain its natural dull copper color when hot. The set consists of numbers 0 thru 8 with the 6 being inverted to make the 9.
