Two handed sword
 

This sword is 1,70cm in length. It was claimed that dates from the 18th century. It is well tempered and holds an edge. But the wight is more than the usuall weight of the fighting swords of this type. It is 4,9kg. What do you think, is this a fighting sword, a ceremonial one, or a 19th century historismus piece?

I think it is a ceremonial sword also called Bearing sword. These were in use until the 17th century.

Almost certainly your sword is a 19th or even 20th century product. It is an imitation of a South German bearing/ceremonial two-hander in style but the details of the parrying lugs, crossguard and pommel are too crude to be the work of one of the great 16th century smiths of Munich and Passau. The weight is correct for a bearing sword of c.1600 - combat two-handers weighed roughly 2 to 3 kilos. I hope that helps.

I agree with Neil. The view of the pommel and tang mushroom says it all. Notice the sharp, precise demarcation between the mushroom (whose top is too neatly shaped to be true), and the crisp countersunk lip of the surrounding hole. This points to an assemblage that is fairly recent.

Thank you all! Very much appreciated!
