As soon as he pulled out the hatchet I started to pucker up. That is some great and scary ingenuity.
To be fair, if he makes a mistake, he's never going to know about it.
From the way he did it, it looks like it definitely wasn't his first time either. Still, not something i'd like to have to do.
The pros are those who live long enough to become good at their task.
The others can't produce videos anymore.
I could imagine the worst case is a single bomblet goes off and the shrapnel just misses all his vital organs. Basically, this is not a job for me.
I'm sure the guy knows what he's doing, the angle grinder and the axe make that clear, but I still puckered hard when he picked up one of the bomblets and started diddling the top part.
