Call it mathematics, geometry ... whatever.
The sword smith, whether an engineer or a village illiterate (like me) ought to thoroughly negotiate these (call them perfect) round lines; specially if there is no slot at the scabbard throat to compensate for those (call them imperfect) ones.
I take it that there are ancient practical methods to resolve these issues without any scholarship, though. Something like building an aqueduct without ending up with the water stopping to run half way to its end; do you know the trick ?
But i digress .
