What is the cane or stick called that slave masters used?

There is no single, specific name for the cane or stick used by slave masters. It was simply referred to as a whip, switch, cane, or stick.

It's important to remember that the tools used for violence and oppression against enslaved people were not unique items but rather common objects used in a horrific and brutal way. This underscores the insidious nature of slavery and the dehumanizing treatment inflicted upon enslaved individuals.
