McClane may never have handled a knife himself, but he has been in knife fights. That is to say faced opponents armed with knives. In some cases holding his own in others winning. Remember he iced a special forces soldier in Die Hard 2 While an icicle is not a knife. The manner he used it in could be translated into using a knife. In the same movie he also held his own against Cnl. Stuart who was both skilled and armed with a knife.
Yes, I know and I was going to make it a part of my original message but then I considered the fact that in his contests with Grant and Stuart (who both had knives) the environment clearly levelled the playing field in those contests. They had to deal with McClane and their balance on the wing of a moving aeroplane. And Grant and Stuart showed no lightning fast moves with knives at all, certainly not at the level of Bonham or Hallam who are proper knife fighters.
In the OP, its in a stable, controlled room and by arming McClane with a knife it is still giving McClane a weapon he has never fought with in his movies. He disarmed the two military guys, yes, but he is not a knife fighter and so the contest is still one-sided because as demonstrated in his films Riddick clearly is.
