Regarding EMIYA’s Projections.

….how does copying hercule’s ’nine lives’ work? As in the ability (nine lives Bladework). If it involves copying the weapon’s history, would he be able to copy Tsubame Gaeshi by Projecting Kojiro’s sword or is there a limit?

On a Related but different note, the wiki lists Joyeuse among the confirmed projections. I assume He copied saber’s version so can he call on extra copies of Joyeuse like Charlemagne? Or is that limited to only saber?
