Why did sake speared spelled his name two ways?

There's a misunderstanding in your question. "Sake speared" isn't a person's name, and there's no evidence of anyone spelling their name in two ways that way.

Perhaps you're thinking of:

* "Sake": This is a Japanese rice wine, not a person's name.

* "Speared": This is a past tense verb meaning to pierce with a spear.

If you could clarify what you're asking about, I might be able to assist you.
