I want to crimp these guys.
Is it better to just not use a ferrule at all if I cannot find the right crimping tool, and just fold the wire on two, or is there a good manual way to do it? I have googled suggestions, and some people suggested pilers, others were against, and so on. So I don't know what is a legit manual way to do it (if it exists).
Also I see there are a lot of tools with different types of mechanisms, which one do you prefer and why? And will a cheap one (that I think I got, but I can't find it), do the work?
