17. Ah, yes, I know the photo you mean...

...of the demolition worker. Those shaped linear charges make a very clean cut and don't blow slag. The metal is literally cut in an instant by the blast wave, not melted by a deliberate process. The guy over at Implosion World gave me the name of the guy in the picture you mention a while back, which I posted in an ancient thread here.

As far as a closeup goes....



Now in one of the threads over at the welding forum, someone suggested that, when cutting a box beam, it is preferable to make a hole, insert the tool, and cut from the inside-out, so that you know you are cutting all of the way through.

But have a look at this 14 second video of an LSC cutting a piece of steel, and the look of the cut it makes:

That's the thing you see positioned at an angle in the photograph you are talking about.
