Signal whip
From wipipedia.org
Signal whips (Signalwhips) are a type of single-tailed whip, originally designed to control dog teams. A signal whip usually measures between 3 and 4 feet in length.
Both signal whips and snake whips are usually shot loaded by braiding the body of the whip over a tapered bag containing weight (often shotgun shot). These whips may also be constructed without loading but it is rarely seen.
The most obvious difference between a snake whip and a signal whip is: a snake whip has a fall (a narrow, flexible, un-braided strip of leather) between the body of the whip and the cracker, and a signal whip has the cracker braided into the body of the whip.
