Some dirks in progress

I love the craftsmanship!
I've never seen a perforated fuller before. It makes sense structurally as a way to reduce weight without losing stiffness. I think it also makes the blade more aesthetically interesting, though that's a matter of taste. Are there historical examples of this practice, or is it a modern, post drill-press, improvement?

I've found a few mostly ranging from 17-18th centuries. Here's an example.

That one was my first and based heavily on Evans. I pray to hold a sheet in that man's wind one day!
