The strongest sword in the Reborn Mod is technically the Mechanical Guardian Sword, but you do need the Guardian Sword (which is the one that the OP was referring to; it could be obtained through a glitch that was patched in v1.3, namely, requiring 1 Wood to craft) to actually craft the Mechanical Guardian Sword it.
