No. Here, I have the Gerber which was said to be the same size as the fallkniven U2, the mini-RSK, the PSP, and a digital camera. You be the judge:
I suppose it would be possible to jam the Gerber in there, at the cost of some of the flatness. It might even be possible to put the mini-RSK1 in there, but you'd probably have to take some stuff out.
A knife should be EDC anyways, since you've always got stuff to do with it. I have a Gerber on my keychain, and the mini-RSK1 in the same pocket.
