"Of course any sharp edge could do in a pinch, and Willow had used them
all: nail scissors, a steak knife, a mans razor- if he doesn't use
safety blades- that's what she'd been carrying when Guy discovered her.
But Willow is a purist. She likes to reserve her cutting implement for
cutting herself alone. She just can't see hacking her flesh with the
same razor she slices her dinner with."
