Manufacturing process.
The author decided to make several such throwing batarangs, so he will use a computer-controlled plasma cutter. He drew the project from scratch, and then multiplied it into copies of different sizes.
He put the disc on the table of the machine, and moistened it.
He started the machine, and after a few minutes all the workpieces can be pulled out.
That's what he did. Of course, this can be done with a grinder, but such a complex figure will take a very long time.
Now he has grinded the cuts and formed the edges.
Then the planes are polished, because the disc was very old and rusty.
Here is such an interesting product.
Of course, it can be sharpened very sharply, because steel allows you to do this.
All good mood, good luck, and interesting ideas!
