Seems to me the force needed to penetrate tracks the diameter, but the strength tracks the area of the cross-section. That is, decrease the thickness by N and it decreases the force needed by N but the strength by N squared. Below a critical thickness, the wire would just break. Spiderwebs don’t slice you up if you run into them.
