I suspect that whatever was available was in use by the folks that weren't nearly as romantic as they are portrayed today....
In fact, down here in paradise (south florida), the southernmost mainland city, Florida City (adjacent to that bustling metropolis, Homestead....) is still pretty primitive by all accounts. It's a mostly farm worker community with a fair share of migrant and transient types. An old time homicide investigator once said that the most common weapon that he found down there, while plying his trade, was a (wait for it.....) rock or bottle, with a few sophisticates using knives or guns.... Yep, just like pirates of old (no matter how the movies show them....).
