One of my knifemaker friends made a few of those. The process itself is very interesting, I was working at a museum when he started to get interested so we had access to some originals as well. Flint knapping is a hoot.
But I'm an anthropologist and as such, a primitive skill buff, other people might find it boring.
You can see my buddy's work here: Diego Attwell - Bladesmith - Arte en Cuchillos
just click on "Galería de fotos" and you'll see three of these flint knives. I can't download the pics from his photo gallery.
I did own the first one, and it's not the greatest cutting tool on Earth. Thank God for evolution!
It does work, though. It's really bad at slicing, but it's a decent hunting knife. It's a replica of an original stone age knife, one could make a more efficient cutting tool with the same materials applying a more modern design, but we wanted to see what the real ones would perform like.
Sadly a coworker of mine dropped it on the floor and the blade broke in three pieces.
Benning, if I were you I'd take that class. It's a fun (and cheap!) hobby. Just remember to wear eye protection.
