Q. In regard to the prohibition of a woman to wear men’s garments, I heard that it applies also to using instruments or weapons that are designated for the use of men. If that is so can a strong woman use a heavy chainsaw to cut some backyard trees?
A. Talmud (Nazir 59a) teaches that a woman should not go out with weapons to war.
Horav Shlomo Miller’s Shlit’a opinion is that if t is possible that in need a woman would use such a heavy tool, there is no prohibition involved.
