Not in the current sense of a decorative knife worn tucked into one's hose. 18th C. (and earlier) women certainly used utilitarian knives in their daily household roles, especially in the kitchen. Maybe they carried one around on a belt for ease of access. There were items known as
chatelaines which hung from a woman's belt and from which all manner of household tools dangled on little chains - thimbles, scissors, etc. So, the notion of a woman wearing a small working knife on her belt is not out of the realm of possibility.
However, she would not wear one away from home as some sort of concealed weapon....
