Guns and knives are not the only weapons available. Back in the early eighties I worked at a fire station on the northeast side of Okc. Responded to many a call in the middle of the night where the female party waited till the man was asleep and poured pots of boiled rice on them while they were sleeping. Seems hot cooked rice sticks to the skin when applied in copious amounts.
Raw oatmeal & baby oil boiled in a microwave works wonders too. Peel the hide right off.
