Need help choosing historical khopesh weapons

[hoplite14gr]

Dear friend the term machera is used loosely by Xenophon.
It does not necessarily means kopis.
If you plan to reanact a cavalryman then yoy need a long blade.
The 14 inch or longer xiphos in the market is historically accurate.

The traditon comes from the Mycenean that used long blades and the tradition was carrie to the aristocratic horsemen of the later era.

If you re-enact a footman, any of these exmaples you presented will do

Kind regards
