2 cents : Found this related github project with a cli tool to split and bind a file : https://github.com/jesseduffield/horcrux

did you make this?

"horcrux" is such a good name for such a tool.

if you drop your email, i'm working on naming something myself.

I didn't make this. I saved it in my bookmarks when found and your post made me remind it, so I shared. I'm really not that good on naming things.
