High profile or really obscure makes no difference. I have to go with the Iron Mistress from the classic Alan Ladd movie of the same name from the 1950s Anyone else? Oh and if you want go ahead and post pics if you want.
the gerber tac II is my favorite knife , i have two , and it was used by kurt russel in big trouble in little china , a close second would have to be rambo 3 bowie and of course the gerber marc II from aliens
Connor's katana in the first Highlander is my fave even though it's not as detailed as the sequals. I also liked the Phurba so much from The Shadow my kids got it for my Birthday one year. Too bad my house got broken into and stole ALL my edged weapons collection.
