All the tools on the Spirit are opened with nail nicks. On the one I've got can all be opened with a single hand. Haven't owned a Leatherman or a knock-off since the days of the original when the tools were on the gripping side with the pliers open.

edit
If you get the Spirit, get the ratcheting plus model. It will use any 1/4" hex drive bit unlike the newer Leatherman models.
