I don't know about Scathach three-sizes. LOL.

Well, the difference between sword (Rhadamantys) and chain (Aeacus) do came to mind when reading their method to discover truth from the dead.

Aeacus keep the dead sit still until the dead told the truth hence the chain. Being the wisest (and most charismatic) among three made such method easy for him-- Rhadamantys on other hand, threatened the dead until the dead told the truth, yet (s)he value justice above all, so (s)he may forgive the dead after (s)he know the truth hence the sword.

Surprisingly both weapon fit Nasuverse as counter kind of weapon given how European Servant tend to have OP Noble Phantasm while Asians Servant tend to rely on technique. LOL.

The blessings is similar to Saber's Invisible Air, so its not a sub-name attached to the sword.
