The tribes carried blades as part of their regular attire, both as a precaution for self-defense and for accomplishing daily tasks.
While the gunong dates back centuries before colonial times, it became more prevalent in 1915 when General John J. Pershing issued an order outlawing the wearing of swords.
Now unable to carry traditional machetes or broadswords, people turned to the gunong to fill the gap without arousing the fears of the American colonial authorities.
More extravagant fittings with chased bands on scabbards, belt clips, guards, and bulbous ferrules also became common.
After World War II, thinner-bladed gunong were made from newer materials like nickel and aluminium.
