Dear Faldage: I wonder when curved blades for cavalry
came into use. I don't know the physics involved, but
somehow more energy can be stored in a curved blade so
that the blow is more effective.
Looks like a typo in the description "linticular" I
think should be "lenticular".

A custom made spatha, of a type for an average auxillary calvary trooper. The blade is of linticular section and the hilt is made from walnut.
