Default Metric Trapezoidal Threads

I need to machine some metric trapezoidal threads. Both internal and
external.

What's the best way to do that?

Is hand grinding the tools going to be my best approach? I think maybe it
is since they are for making molds of two mating parts. The molds can't be
of the exact thread forms or the parts won't fit together. A proper cutting
tool for those threads might not produce what I need. I'm still thinking my
way through the process.
