I have saw this "tool" on YouTube and here on forum.
Tried this method of blade straitening with a broken carbide endmill held in a drill chuck, even with that setup I was impressed how well it worked.
Then I googled to buy a hammer with a carbide face, they aren't cheap and not sold locally (not even in Europe let alone in Serbia) so I would need to add shipping and customs fees to the price, that ended up being too much...

Soo I picked up an old ball peen hammer head, that I already had. (I always buy these at yard sales and similar places when I see one, I think this one was 2 buck or less)
Got on a Chinese website and order a 10mm carbide ball (If I remember it was 3-4 bucks with shipping)

Put the hammer in the HT kiln, annealed it, then drilled it out to a specific depth (also cleaned the old hammer)

I brazed the carbide ball with brass

Made a plum wood handle (went a little fancy, plum wood is really popular in Serbia, there is a famous drink (brandy) "rakija" made here with plum fruit)

I have tried it, works really good. I do mostly plate quenching, soo not that many bent blades, but still nice to have it!

I got 2, 3/8" carbide balls on Amazon and 2 Vintaj 8oz Ball Peen hammers from Amazon and made 2 yesterday. The Hammers are cheapo's (one of the heads is loose, too), but I saw reviews that the heads were soft, so they were easier to drill. I used a 3/8" natural stone type bit to drill into the flat face and then put the ball into the hole. Hit it on some wood and then metal and the balls are stuck in the hole now. About $33 to make 2 hammers. I will see if the balls fall out and need to be epoxied back in after they get some use.

Natlek, the hammer will leave small marks/dimples on the surface of the steel, so it's best to use them before it is fully ground, or you may not be able to fully grind the dimples out.
