Hi Jim!

I prefer the small scissors on the SAK for precision work. The SAK is rounder and feels smoother in the pocket, and it's also lighter. Most importantly though, I find the SAK is easier to use... no need to unfold first then pull out the implement while the scissors are in the way, like for the Micra. That SAK also has a retractable pen.

The only reason I would go back to the Micra is for durability (all metal) and the stronger and larger scissors.
