I use one paperclip per week, and the only time I have one with me is when I'm doing that one thing on Monday morning. Other than that, there's one bowl full of them which is actually in the same room as the pile of miscellaneous stuff that includes the real sim ejector gadgets.
I carry at least 2 paperclips with me (1 live, 1 backup). They don't add much to the space or weight of my EDC, but they can come in handy in the time of need.
ergo, I keep a spare ejector tool on my keychain for this very reason.
