javelin is more efficient then the blackbird, it's efficiency² but still a smooth razor (YMMV). Been enjoying it a lot lately, trying out all kinds of blades.
Favorites so far: Feather - Gillette blacks - Nacet - PermaSharp - Polsilver - Super Iridium.
I've become quite fond of the handle, something I didn't expect. Have no idea if Andrew is going to produce the javelin or when but I hope so.
Last I heard of him was this message: Hi Ron — I am working on a new DE, which is actually pretty different from 17-4, but should be better. I don't want to say too much about material, design, release date, because those are fluid.
So I guess patience ....
