Oy Tikkakoski Ab was a Finnish company producing firearms and different consumer durables, most notably sewing machines.

The company was founded by Martin Stenij as a metal workshop next to the Jyväsjoki mill and saw, but experienced several bankruptcies and changes in ownership as a result.

In 1930, the company was purchased by a German armsdealer Willi Daugs and the next year the production of the Suomi KP/-31 submachine gun was started.

After the war, Tikkakoski was considered to be a German-owned company and its assets were confiscated for the Soviet Union in 1947, discontinuing firearms production and focusing on sewing machines.

[3] Later, Tikkakoski was omitted from the company name but SAKO continues to use the Tikka brand for a series of rifles, mostly the T3X model.
