The name of a Russian whip is the "nagaika." It is a traditional riding crop or whip commonly used by Cossacks in Russia.

The whip that was used in Imperial Russia as corporal punishment of criminals and political offenders is called knout.

It was used from the 15th century till 19th century.

The great knout consisted of a handle about 60 centimetres (24 in) long, to which was fastened a flat leather thong about twice the length of the handle, terminating with a large copper or brass ring to which was affixed a strip of hide about five centimeters broad at the ring, and terminating at the end of 60 centimetres (24 in) in a point. This was soaked in milk and dried in the sun to make it harder.

The victim was tied to a post or on a triangle of wood and stripped, receiving the specified number of strokes on the back. A sentence of 100 or 120 lashes was equivalent to a death sentence; even twenty lashes could maim, and with the specially extended Great Knout twenty blows could kill.
