Going through some old files and found a nice picture of a Bagobo forge. The Bagobo ethnicity is established by the pants worn by some of the workers, which show the typical Bagobo beadwork much favored by Bagobo men.
The forge resembles most other ethnic groups in the Philippines, with a relatively small hearth and double-piston bellows powered by the guy sitting on top them.
Note the variety of blades being produced, several of which resemble the man's working knife shown above. Most of the swords are forward-weighted, fat-belly bolos.
