I have spyderco Dragonfly for really compact carry. Great ergonomics.
I just added Doug Ritter mini RSK my 1 gen 2. Pretty much a mini grip with a 20cv blade shape I prefer. Being a lefty I really like the axis type lock.
I was really considering a James Brand, carter. Very nice looking and Micarta handle and lefty friendly. But pricy for vg10 blade steel.
