I can see it playing out this way. She more than likely would not be able to do actual lasting damage to the guy, but she can probably distract him.
Say there's a Dude standing out in the open and there are two people, person A and B. Right now, the Dude has all of his attention on person B.
Suddenly person A sneaks up on the Dude and jabs him with a small sewing pin. It doesn't actually do any damage, but it's insanely annoying which leads to the Dude putting his focus on person A.
While the Dude has attention turned, person B rides up and absolutely knuckle dusts the mother fucker with a shiny pair of Brass Knuckles. Which would lead to a more devastating and more guaranteed result compared to person B trying to do this head on.

Or it would just lead to Kaido doing this...
