Daken is not his father his pain tolerance is significantly less then wolverine's and i would say even Frank... its a personality trait just like 753 said.
i will admit frank did pretty good and was impressive with his adaptability improvisation against daken who whas just toying with him or he would have simply disappeared on frank with his speed and pheromones and one shotted him for the kill.... or removed his hands b4 frank knew what was going on.
