I have some rather large wire ties (or, as heathens would say, “zip ties”) that would do a pretty good job, the advantage being the victim is deprived of vocalization, should lose consciousness rather quickly, and the blood stays inside.
Writer here. I was once looking for a feature image for my article about teenagers and tobacco use. I did a search for “smoking teen girls.” Won’t make that mistake again.
Google is much better now, I just tried that search, with and without quotes, and it gave me pictures and links about teen girls smoking. I don’t use safesearch settings.
