In woodworking, a spline is a long (and perforce rigid) bar of material
used to join two grooved work pieces (essentially acting as a two-sided
"tongue"), running cross-grain and providing greater strength than a
simple butt joint by greatly increasing glue surface area. I suspect
the same sense exists in metalworking as well.

With that as a starting point, I find the woodworking use of "spline" here.

I wonder if the woodworkers know that a "spline" means a curved line?

A spline is ALSO a curved line.

You do realize that many words have many different meanings....

Consider, leaves, race, etc.
