fists and saps
"Beavertail sap" is slang for a type of close-quarters, weighted impact weapon, also known as a slapjack or blackjack. It's a leather-bound tool with a weighted end that resembles the tail of a beaver, hence the name. These non-lethal weapons are designed to deliver a concentrated, forceful strike and are known for their concealability and portability.
