H47,
Welcome to the forum, and you are correct, those red fluted chisels are from T-dad. I made them in "89"as part of Ed Shulin's stockmaking class. (in "73" I was still trying to figure out how not to fall of a tricycle,although I no a guy from Montana that made a nice set there in the "70's"). As I remember Ed had a box of that fluted handle material,red and blue, it was in 3 foot lengths and you could just chop of a piece, shape and install right there on a lathe in the stock making shop.
I have about 60 strait chisels and gouges collected over the years but the only scrapers I have are the one's made in Ed's class. I have never seen them commercially made for sale.
Here's a pic of the original set.
