Pulk
A pulk is originally a Nordic term for a low-slung boat-like sled, sometimes without runners, capable of being pulled by hand on foot or skis, or by light draft animals such as dogs or reindeer. A toboggan could be called a pulk. They are classically made out of wood and other natural materials but are nowadays made of plastic, which makes them inexpensive.
Pulks are originally meant to carry supplies such as a tent or food, or transport a child or other person. In Norway, Finland and Sweden, pulks are often used by parents to pull small children on skiing trips. In Finland and Sweden, pulks exist as a winter toy, mainly for children, for going downhill.
Akja
A larger pulk, designed for transporting larger amounts of goods, is called a akja. The term stems from older Sami akio, akje and, akkio, akkia, which in turn is a borrowing from Proto-Norse, cognate with,, "driving, fording", to the root ak, "drive, ford, ride", ultimately related to "act".Listed old Sami synonyms includes: geres, kerres, låkkek and pulka.
