Tanto-style blades, from a 30mm APC cannon. In the center of the roller from the bearing. The steel is heat-resistant, so it is very difficult to forge.
At 0:22, a section of the barrel is shown, where you can see that the hole is not drilled in the center. Why this is so, I do not know, maybe such technology or workmanship.
Thank you all for your support in the comments. I'm still relatively safe as well. Today is the 305th day of the war.
