In the movie "Romancing the Stone" I thought the bad guy General ends up with Cathleen Turner

JOAN WILDER deploying a knife through his hand.
Any body ever seen the movie and know what knife it is?
Oh by the way it happened in the last like 10 minutes of the movie.. just before the Crocodile takes his arm off just below the elbow.

I don't have the movie and do know he carried a switch blade. May be the knife didn't get deployed into his hand.
Been a while anyway it was just movie trivia probably belonged in open topic
