There are examples where spacing / tolerances of the threads give some limitation.

The Paradigm 17-4 comes with M5 thread. The fit between head and stock handle is very subtile, threads run smooth with almost no play. On the other hand most of my other handles from Triad, Stork and other manufacturers and artisans do not fit the 17-4 head as the tolerances of the threads are to small.

As others have said, the majority of older razors 10-32, and most newer handles are M5x0.8.

If you were to tap the handle at M5x0.8, you will have something that will work with most heads, Just not the Fatip. The fit may not be as snug and precision feeling as say a Paradigm or Raw razor.

A head threaded at 10-32 will fit with most handles 10-32 and M5x0.8. It might just not be the precision fit of the high end razors if using the M5 handle.

The Fatip is actually smaller, not larger as said earlier. I believe I have read it is M4.5x.75 but don't quote me on that. I just know it is smaller.

Tough to find something that works for all of them. The closest is the Weber Bulldog or older iKon Bulldog polished (which I think are the same handle other than a logo). They are barely small enough for the Fatip, but large enough for most modern heads. I doubt they would be large enough for a precision M5 head though. I will try and check with a Paradigm tonight. Not sure they are M5, but it feels big and precise.

If I were going to try and make handles for sale, I would be looking for a niche of jist being small enough to fit the Fatip. Fatip owners are hungry for nice handles, moreso than Paradigm users are hungry for nice handles, and if done like the Weber, it would fit most moderns. . ..but I don't know what size this is, or if they went with something custom to try and be universal. If your friend is just making one for you, I would go with the M5 (unless you are a Fatip fan).

For the sake of completeness, I know that GEM and Everready heads have female threading. 10-32 on the newr ones, but the older ones (like 1910's and 1920's) have the odd 8-24 or some weird similar size.

Actually, It's not that easy.
Unfortunatelly It depends on each single model of Fatip if match or not the single model of handle of choice.

Into my domestic forum in Italy, there're some experiences:

My advise too is go with metric.
M5x08 is the most used.

In most cases, the standard size M5x0.8 is used. This handle fits almost all heads, you can make a little mistake, nothing terrible will happen. This size will fit without any problems. I work in a barbershop, a friend of mine is a handle supplier. He makes them himself, measures them with a ruler, pretty quick and good quality. I've seen him make this handle, it turns out very nice, most of the time I put them on Paradigm. You can also use Fatip, but most customers don't like these heads.
