When I cut all thread and need to clean up the end I use coarse sand belt on my 1" belt sander. Simple twirl of the all thread at an angle and the end is cleaned up.
Seems extremely expensive even at the 50% off price. It would be hard to sharpen because the threads are internal and it will need sharpening fairly often if you are using steel bolts.
Also it will be hard to hold the bolt straight and aligned with the tool axis due to the head of the bolt making it hard to mount in a machine like a lathe, although it looks like the tool itself could be so mounted. Maybe you can hand hold the bolt and mount the tool in the lathe headstock chuck.

In the trades we use a good old fashion flat file.

It would appear that this tool is made with some kind of high quality tool steel ... possibly up to the same as the grade 8 that is mentioned as the highest it should be used on for hardness. Somewhere around rockwell hardness 70.
It has some kind of "coating" on it with a supposed hardness of 92, to make the tool's edge work more efficiently in removing the thread and burr and helping keep the tool's edge sharp.
If you have a small diamond file, you could probably get in there by hand and re-sharpen the edge from the outside...
It says that it cannot handle Chrome/Moly steels, however ... which might actually indicate that the material that it is made up of may be lower in hardness to it or the same.

I always used my tap-n-die set and cleaned up with a flat file like john mentioned.

when I have to cut a bolt or threaded rod I run a nut up on it first. After the cut a little 150 sand paper then unscrew the nut. Cleans and realigns the end..
