Feather AS-D1 handle on ATT head?

The standard and metric thread pitches used on modern 3 piece razors are close enough that they are interchangeable. The older Gillettes (eg - Tech) are not, however.

Is this still true for AS D2?
ASD2 is also metric M5 x 0.8 thread.
Suitable for most handles. Including ATT handle.

It should be noted that some American and Canadian brands, such as karve and rockwell, still use 10/32thread.
10/32 is slightly smaller than M5, so the M5 handle can also be used to fit the 10/32 head, but it is slightly loose; the combination of the 10/32 handle and the M5 head may be too tight, and it must be carefully tried or even avoided to avoid damaging the thread.

There is also weird fatip, which is different from anyone's thread, and it is difficult to freely change the handle.

Single edge versions too?
