Lefty here. Kershaw Iridium is great, fully ambidextrous, and the clip can be mounted on either side. I also used to have a Spyderco Dragonfly 2 that was excellent and small, a great everyday knife to keep in the watch pocket of my jeans. Wish I knew what happened to that one!
And if you’re feeling more…frugal…I still regularly use this Gerber EZ-Out Skeleton that I bought in the year 2000. The steel is nothing special, and I don’t think the clip is reversible, but otherwise also good for lefties:
