Corrected entry: Towards the end of the movie Arnold swims out of a pond onto a log. Before he can fully emerge the Predator stabs his retractable knives into the log, conveniently fitting around the width of Arnold's neck. The next angle you can see this better when the Predator is directly over Arnold, the knives have a huge gap between them. The knife prop was obviously made just for this scene, because later on the Predator uses the knives again and they are at the normal width.

Correction: It is deliberate - the predator didn't want to kill Dutch straight away, it wanted to examine him; presumably because he had been such a formidable enemy.
