Ivy…
its not a knife, but the whole cutting your panties off, and that extra set of hands…
its a button pusher.
Uh, buttons definitely pushed.
And scissors are definitely two knives hinged together so it counts for me.
Also, I’d just like to share that the tag on this was “pointy things and girly panties inevitably make me think of Ivy”. Which is just the best tag ever.
