A bismar (or desemer) is a simple balance with a weight at one end of the beam, a load hook at the other end, and a moveable fulcrum in between. This example is made of steel. The side of the beam is stamped in a circle “MARIEFORS + KELLOKOSKY +” and the weight is stamped with a crown and “1946 2.”

Kellikosky is a village in the Finnish municipality of Tuusula; Mariefors is its Swedish name. An axe factory was established there in the early nineteenth century.
