Lyric discussion by drfunk 

eatmydonuts the hammers are a symbol as was the swastika. Notice they have similar colors and layout. The hammers represent oppression by force. The word 'hammer' is referenced many times throughout the album.. 'And the hammers batter down the door' and 'Let me hammer him today'. The hammers are used in the movie as hitler used the swastika to promote his growing army, a symbol of strength and power. (Hitler choose the swastika symbol because of its use by the ancient pharaohs of egypt who used it as a symbol to force millions of followers to build pyramids and structures) I also believe the hammers were choosen beause they represent both destruction and construction. You could argue the hammers were a tool representing his building of the wall.. and later the destruction of the wall. It is no secret there is a military theme carried out through this part of the album. When waters sings 'Waiting to put on a black shirt' he is clearly refering to Mussolini and his black shirt army. And of course he references Hitler when he says 'Waiting for the final solution To strengthen the strain'. Hitler and Mussolini play a big part in this song because pink struggled to understand how one person can command so many to commit acts so unthinkable... I think this coupled with the loss of his father caused him to hate what he had become in his mind.

additionally i believe the worms are to represent the decay of pinks mental state. They also represent the millions of jews that died in the hollocaust.
