In [[1935]] it was turned into a war industry. Towards the end of the Second World War it was destroyed by bombing, and the remains were later dismantled by the Red Army. The company was refounded with offices in Berlin and Frankfurt, but later the Berlin office was confiscated by the authorities of the Soviet sector of the city.

In [[1935]] the company was converted into a war industry. In [[1945]] the Oranienburg production facilities were destroyed, the remains dismantled by the Red Army, and the plant was nationalized. VEB Kaltwalzwerk Oranienburg was established at the site, which was modernized several times and produced cold rolled strip. The Georgenkirchstraße factory, which now belonged to East Berlin, was confiscated and became the property of the people (VEB) in [[1949]].  

The Frankfurt site remained in the ownership of the Blanckertz family, continuing to produce instruments for writing and fine arts. The Berlin location, on the other hand, became [[1949]] the [[VEB Berliner Schreibfeder]] ('VEB' stands for state-owned enterprises).

<noinclude>The company was reestablished in West Berlin, but later moved to Frankfurt and then to Wehrheim. With the advent of the ballpoint pen, the market for nibs was reduced to artistic drawing and calligraphy; today the company is still active, operating mainly in the field of artistic crafts and drawing.
