I'm only going to take one shot at this as there seems to be a lack of willingness--not ability--for many people to engage in anything approaching maturity when conversing on this subject, but...
No, you're not likely to stab a barrel in real world use. However, you might be stabbing something else--especially with a large tanto, as a strong tip which still has great piercing power is the whole idea behind that design. Ribs, as hard as one tries to miss them, have a bad tendency to get in the way of a blade entering a torso, and can ding up a less-than-optimal point/edge geometry fairly badly (one of my friends lost the front 3/8" off the point of his SOG Desert Dagger inside of the hog he was killing last year).
My question, had I just come across this knife on a table, likely would have been how the hollow grind would hold up under impact use. Honestly, combine the hollow grinds and the sawback--two design features that can very seriously weaken a blade if not done correctly--and I'd have been worried about the front 3/4" or so of that blade snapping off on that drum, especially since many of those stabs glanced a bit and went in at angles that were a long way from being parallel with the direction of the force. The fact that no gross damage occurred from this type of abuse inspires confidence that the knife wouldn't fail in the real world. That's the whole idea behind testing products of any kind: subject them to stresses greater than what they'll face from the average consumer, and see where the limits are. Now this wasn't really a test, as the limits weren't found and there was no way of collecting repeatable data, but instead a demonstration of the toughness of the knife. Does this one demonstration mean that it's the awesomest, bestest knife ever to land on the planet? No. But, there's a whole hell of a lot of knives that couldn't do it. Also, the grip security seemed to be very good under hard impact, another point a potential buyer might take interest in.

If your response to it is:
"I'm not sure why you would ever cut so many small squares of paper in a 'sicing use' type situation"...your parents should have beaten you more.
