I've never seen a tool for doing this. Conventional bicycle spoke threads are always rolled.
It's not something I know anything about, but it must be a thing, it's discouraged in Roger Musson's Wheelpro book:Obtaining the appropriate spoke length by cutting the thread into a trimmed down spoke using a threading die is not an ideal solution because it disrupts the grain flow and the smaller thread diameter will not be an ideal fit in the nipple…
well that would have some meaning if you were comparing rolled threads with cut thread in a more general sense but it is misleading in relation to bicycle spokes.
I repeat, bicycle spoke threads are always rolled not cut, (it is physically impossible to cut a 14G spoke thread in a 14G spoke) and the 'grain flow is disrupted' in the same way whether it is an inexpensive rolling head or a tool that costs x100 more.
Needless to say it is possible to make a mess of it with whichever type of tool too, or fail to stress-relieve the spoke properly, or one of a hundred other things.
