The wire twisting pliers in the first picture are used for lock wire, not electrical wire and they are very good at that specific task. Used in industries such as aviation to prevent movement/rotation of a fastener or a part such as a screw on oil filter.

Yeah but they they're usually too big for the work I have in mind, and not nearly as smooth as a potential pump-action equivalent.

Yea one of the flaws of traditional safety wire twisting tools is their size and inability to get into really tight spaces. The solution in the article still seems too big. I'd buy something like it but only if it was the size of a small ratchet.
