Many of you may not know that Gil Hibben is the official "Klingon Armorer" and he designed the edged weapons use by the Klnigons and others in the Star Trek movies. If you visit the "Star Trek Experience" in the Hiltom Hotel in Las Vegas you will see many of his knives on display.
If you buy the "Generations" DVD, one of the added features is about Gil and the knives he designed for the Star Trek Movies.
version of Gil's "Jackal" knife is seen above. Below is one of the actual knives
used in the movies. The blade was painted for photographic purposes.
