Yes I have better stamina but the nature of the weapons does not rationally support a larger stamina requirement. This is simply an arbitrary penalty and I hate those. The features of a device should follow the nature and material of that device.

Iron is both lighter and stronger than Bronze, and there is no rational reason for it to demand more stamina in its use. Copper is far superior to stone in handling requirements and should be far less demanding of stamina.

Refined weapons should have less of a stamina demand than cruder versions.

Gamey things should be avoided in design.
