I'm relatively fluent in Japanese, and to my knowledge the character "著" is usually only used for authors, though I admit I could be wrong. I actually can't think of anyway to translate "by Imeo" very well. I think that on swords and such they usually just engraved the makers name, and possibly date, place etc.
Of course being a non-Japanese name it should be spelled out phonetically in katakana, probably "イメオ", presuming I'm pronouncing his name correctly, but not knowing Greek phonetics I could again be mistaken.
