His materials from all the way back in Fate Stay Night Visual Novel states thats Caladbolg EMIYA projects. He puts it through Alteration magecraft to turn the sword into an arrow. As for why it looks closer to Excalibur than the actual Caladbolg, I suggest you bring up the issue with the designer(Takeuchi Takeshi, co-founder of Type-Moon).
