In the 1976 movie Marathon Man the British actor sir Laurence Olivier plays Nazi dentist Christian Szell, and his weapon of choice is a wrist mounted automatic blade:
In the 1981 movie "Eye of the Needle" actor Donald Sutherland plays the German spy (code named "Nadel") who regularly uses a rather large spike-like stiletto on his victims.
It seems that such stilletto's really existed and were made by the Italian manufacturer Due Buoi, and that they were carried & used by agents of both Italian and German intelligence services during World War 2.
In the classic 1972 movie Jeremiah Johnson the main character was played by American actor Robert Redford.
Besides his .50 caliber Hawken rifle he also carried & used a Western Bowie knife.
Below is an actual prop knife used in the movie "Jeremiah Johnson" by Robert Redford.
The knife features a 14 3/4" overall length plus leather sheath & is made from painted rubber which was aged by the studio for the production.
A while ago i made my own version of the Jeremiah Johnson sheath to go with my 1964 Western Bowie:

Most likely unknown outside the Netherlands is the 1972 movie "De Inbreker" or "the Burglar" in English.
In it then major Dutch actor Rijk de Gooyer plays Willem "Glimmie" Burg, a skilled burglar and jewel thief, while his friend and bodyguard is played by real-life martial artist and actual Korea war veteran Jon Bluming.
Recently i discovered a 1080p HD upscaled version of this personal favorite on Youtube, and it even has English subtitles.
The main character's stiletto plays an important part in the storyline, and for his role as old school underworld figure actor Rijk de Gooyer learned how to handle as well as throw that stiletto like a pro.
Entirely shot in old Amsterdam, and complete with scenes in the Red Light district (with actressess instead of prostitutes)
