Wrought Iron and 15n20 san mai with a 3D printed high density ABS plastic handle.
I was a bit weary about the plastic (customer couldn't afford cast bronze or brass), but it's quite resilient... ask anyone that's stepped on a Lego.
Only flaw is it's TOO white; every speck of dirt on your hands is drawn to it like a magnet. I combated this somewhat with several layers of aerosol lacquer. The plastic weighs nothing even though it's solid and the tang runs all the way through the handle.
This project was a metric snotload of fun. It's based off my favorite monster, from my favorite video game... so sad it belongs to the customer. Maybe I'll reforge the blade and print the handle in bronze for myself, hehe
