there's nothing wrong with demonstrations that border into the hokey. but to say that other more expensive products "can't even do this" is bad advertising. in this day and age, few people find the need to cut manila rope; and meat buchers use far cheaper knives to better effect.
but i do agree with the mention that many fanciers of other brands simply like to own awesome stuff. i own one cold steel product. i think it's awesome. and i hardly use it.
as regards my other knife brand that's famous for simply being awesome, i never thought i would need to take it out over lunch just to cut a stubborn pork chop but i did. VG-10 is awesome regardless.
