homemade scythe anyone ever made one?

Hello everybody,

Here is my prototype.The teeth don't seem to cut very well.Thinking about ripping teeth out and sharping bone.Also considering using a rib bone.Has anyone ever made a homemade scythe?ever sharpened bone?

I have sharpened bone before.  Word of caution: wear a good mask.  Don't breath the stuff.  Animal product in your lungs leads to some very serious 'bad juju'.  Like mineral dust and other non dissolvable fibers, it can give you long term health issues; but it can also lead to some nasty infections.  Guys whom knap or shape bone for arrow heads have learned the hard way to take every precaution to keep from breathing bone dust.
