No too sure about this one

Hi All,

The dagger blade appears to be one of the many fleur de lis iron fence finial variants. When you think about it, cast iron is harder and can take a keener edge than steel. The increased brittlely of cast iron is irrelevant in this context due to the thickness of the blade and the lack of armor of the intended target. Given that, a sharpened fence finial could be a very lethal weapon. We need fence control!

Sincerely,
RobT
