Athens Kopis

[Velites77]

Hello,

i'm looking for some information about the Kopis in the national museum of Athens, the subject has been already discussed here but i would like to know specifically in which way the hilt is attached to the blade,

from the few pictures available i cannot figure out if it is sandwiched to the tang or cast in single piece, or may be a combination of the two methods

also which material it is? bronze? iron?

i would be very grateful also if someone can provide a drawing or better photos of the kopis

from what i know the sword is without scabbard, do you know if there are surviving archeological evidences of kopis scabbards?

thanks for your help
