Now I'm confused. A war-scythe, as far as I'm concerned, looks like [url=http://www.discoverthemiddleages.com/img/full/War%20Scythe%202.jpg]this[/url] and was essentially used like a poor man's halberd, sort of like your description when it comes to cutting and piercing armour. However, that doesn't go with the visual image I have from your description. Something like [url=http://upload.wikimedia.org/wikipedia/commons/2/26/Sickle_and_scythe_labels.jpg]this[/url] is highly impractical and I have no idea what you're going for anymore.
