A "Oaxaca knife" from the 19th century typically refers to a style of large, heavy-bladed knife or dagger, often with a distinctive handle, that was made in and around Oaxaca, Mexico. These knives, sometimes referred to as "Oaxaca swords" or "Oaxaca Bowie knives", often feature bone or horn handles, brass bolsters, and a large steel blade. They may be engraved with Spanish phrases or depictions of eagles.
