Just curious, the president's pens

Everytime I see the President sign something, even the same report, he uses a different pen for each signature.

I have noticed this with Barack Obama, I don't recall this with former POTUS's but it doesn't mean they didn't do it.

Why do they use a new pen for each signature?

Thanks for the info!

Thanks for asking this question! I was wondering this also but had not got around to posting yet. I can not wait to find out the answer. It is also the first time I had noticed it.
