Claire and the Kantschu by K. Gray, StrictWorld

*Kantschu (Russian: nagyka, nagaika, or nagayka) is the German word for a short, thick whip with round cross-section used by Cossacks, borrowed from Nogai people, hence the original name “nogaika”, or “Nogai’s whip”.[1] It is also called “kamcha” from the Turkic word “kamci” for “whip”. The latter word is also used for short whips of Central Asian origin (Wikipedia).
