German to English Social Sciences Archaeology military implements of the Roman Empire

This is a description of machetes (Haumesser) in a Roman military camp. It is presented here as an example of a fascine knife, others having been previously discussed:

Daß aber auch andere Formen besonders in frühem militärischem Kontext vorkommen, zeigen Haumesser mit mittig an der Klinge ansetzender Tülle, mit **Schaftlappen** oder mit geknicktem Rücken aus Militärlagern der Okkupationszeit in Germanien.

My draft:

The fact that other forms also exist, especially in an early military context, is shown by machetes from military camps of the occupation period in Germania, which have a shaft socket centered on the blade, with shaft flanges [??] or folding backs.[??-next query is on this one!]

Many thanks, if there's an archeologist out there!
