Breakable sword prop

Breakable sword

This breakable sword prop was made for the 2004 State Opera of South Australia production of "The Ring Cycle". This breakable sword needed to be able to be swung about like a real sword and then, at the press of a button, break in two.

 

The mechanism was designed and built by David Wilson and was integrated into an existing sword handle. A spring-loaded collar holds the two custom built blade sections together. Pressing a lever on the hilt retracts the spring loaded collar allowing the end section of the blade to fall to the floor.

 

Breakable sword prop construction

All the steel parts for the breakable sword prop were laser cut from DXF files produced from the CAD drawing shown below. A more detailed description of the construction of the prop sword shows how the parts in the drawing relate to the finished item.
