as long as she can fire it off. Some of the MicroTech autos have a very stiff 'trigger'. My wife can't manipulate any of my MicroTech OTF knives.
This is an important consideration with any OTF. I have some OTFs (not Mictotech) that I don't even think about opening. But my GF and one daughter can't open without two hands. My other daughter can click them open and closed but I can see she is struggling a little too much.
I would recommend an OTS. Anyone can press a button and a knife should easily deploy when needed. Who cares if you need two hands to close it later.
