Everyone was surprised by the news.

My boyfriend gave me a gift.

He scattered caltrops on the ground.

He is called the iron general of chess.

He is a railfan, and goes to take pictures of the Shinkansen every weekend.

This scrap iron can be recycled.

This tin toy is old, but it still works.

He tried to open the door with an iron pipe.

Onitetsu is my favorite band.

What should I do to remove this iron rust?
