By the Red Gods, that's exactly what he did: sharpened the shaft with a pencil sharpener and glued on craft knife blades.
Wow, I've never seen anything like that and especially never seen anyone try to sell something like that.
I guess you really can find anything on eBay!

I don't think those nocks are heat treated. I suspect he's using a power tool of some kind to cut the nocks and it is building up heat either through being dull or being pushed too hard and not letting the tool cut properly.
When I was making and selling custom wood arrows one of my options was a self nock or a horn reinforced self nock. I didn't charge a lot more than this fellow but I can assure you the nocks were a whole lot different!
