What is this thing called?

[B_Bimmer]

This came up in one of those random videos one occasionally sees on the internet and actually looked to be a pretty decent idea. It's purpose is to taper threads on cut all thread and bolts to allow for an easier start, without fiddling around with putting a nut on before cutting or other higher maintenance methods. I thought I would be able to find it but as of yet haven't had any luck. Is it a real product and if so what's it called?

I think it's a great idea, and I'm always keen on buying new tools, but I've been using my 1" belt sander to do the same thing for the last 40 years.

Just sayin'...

Damn, another tool I didn’t know I needed.

We cut crosses in the ends of the bolts and carefully, with a sharp chisel, peened them into a taper.

A light touch on the bench grinder has always worked for me.

Followed by a hard touch with the wire wheel. Grinding always leaves a burr you don't want pushed into the thread valley.
