The Falx

[Magnus]

I don't think for a moment though that a falx could cleave all the way through a scutum...more a glancing blow that then went on to hit flesh and bone is more likely the cause of the embedded wood in the bones. There's just too much resistance given the breadth of a scutum to go through that and then a target behind. In the picture tarbicus posted, Steve wound up and hit that scutum (authenticaly made in 3 layers of strips btw) and it sank in just under a foot. Steve's a solidly built guy too.

I don't think they're much of a parrying weapon...more of a shock and awe "let's make a hole in the line here" type.
