Simple electrical wire joining technique - GIF

[Frank S]

Speaking of joining wires, real wire vs plated impersonators. I don't buy imports of certain Asian countries; but there is one worthy of copying.
Tying splices or circuit branches are the tasks for which it is suited. Can't see it plausible for stranded or plated, just solid wire.

Wire nuts are very accepted, used 100's myself, but not 100% sure a tapered bundle in a tapered hole is mechanically sound.

The tapered spring inside the better wire nuts do make for a mechanically sound connection, but not where movement and vibrations of mobile applications are involved without care being taken to secure them from movement. As with any electrical connection each has their place and each type should not the considered for the wrong application.
