On "おてもと" and its many variants for "chopsticks"

Question

I've always known the Japanese word for "chopsticks" to be (お)箸{はし}.

Today in my usual practice of reading everything around me I looked up what was written on the wrapper of the disposable chopsticks that came with my supermarket bento:

おてもと

I was firstly surprised to find out that it's another word for "chopsticks", and secondly on looking up WWWJDIC that it has many variants:

おてもと 《お手許; お手元; 御手許; 御手元》 (n) (uk) chopsticks (often written on the paper wrapper)

From this I can see that it's usually written on paper chopstick wrappers and that all the kanji forms are uncommon, but nothing else.

I'd like to know the origin or history of the term. Does it have any other current uses besides on wrappers, was it more common in the past? And why does it have so many variants? Obviously the initial お is the honorific that can also be written 御, but what about the two possible final characters 許 and 元?

Answer 1

おてもと does refer to chopsticks but it is not "another word for chopsticks." That is, you won't say おてもとを取ってください nor 新しいおてもとを買ってこようかな.

According to the source article that Chocolate's Wikipedia article mentions, the word came from a reference to "お手もと箸" (chopsticks for your personal use) in contrast to "お取り箸", which refers to chopsticks for shared dishes that you use to bring food from a shared dish to your personal dish.

Good question about お手許 vs お手元. I couldn't find any source that tells me how those two uses came about being, although I suspect this kind of writing variations aren't all that uncommon.
