ふたりで一人前で meaning


> ふたりで一人前 **で** いろんなものをまっぷたつにするのは何?

What is the thing that can cut in half various things when the to parts become
one?

This is my interpretation, but I think is wrong.  
Can someone explain?  
Especialli the bold で.  
Is it the continuative of です or the で of means?




  * That で in bold is the continuative form of the copula だ, as in "私は会社員 **で** 、妹は大学生です". So it's basically "and".
  * 一人前 in this sentence means _full-fledged_ , _mature_ , etc.

  * ふたりで一人前 literally means "(becomes) full-fledged by two people" or "full-fledged when there are two people". Riddles often use personification like this, and it just means "works fine only in pairs".

The whole sentence roughly means "What is the thing that works fine only in
pairs **and** cuts various things in two?"

The answer of the riddle is probably "scissors".
