On the Busse Video for the Stealth Hawk, it shows the knife being used to saw cut 1/2" rope, what appears to be hemp rope.
Shows the knife beaten through the lid of a fifty gallon drum and driven through some 2"X6"'s.
That should be available some where on the historical part of the internet.
I'm guessing I'd need a Gold sash in google-fu to find that!! But I'll try...
Impressive nonetheless.
