Using a branding iron to apply a brand is the most charming and traditional manner in which a name or logo is applied to a cutting board. This process actually uses a hot iron to burn the wood. This hand done branding can result in some slight variations from board to board as a human is incontrol of the hot metal. It can also be common to see a "halo" effect where the heat near the irons head burns the surrounding wood.
One of the best features of this process is that the edge of the board can be branded.
