Veeg, the Muppets Take Bosnia? Is that from the same film company that brought us films like "Bambi Goes Crazy Ape Bonkers with His Drill and Set" and "Littlefoot Finds a Mate" (oh wait, that's a real movie)?...
In Seven, Detective Somerset (Morgan Freeman) flicks out a cute little automatic to cut through the paper backing of a painting, much to the surprise of his partner, Mills (Brad Pitt).
Mills: What the **** is that?
Somerset: Switchblade.
I just love that scene, largely because Somerset's so matter-of-fact about it. There's no macho posturing, "I have a big mean eeeevil switchblade, I cut you, I cut you like a fish", it's just "switchblade, duh."
The scene in the very beginning of The Seven Samurai, where Kanbei (Takashi Shimura) shaves his head. I guess I just like scenes in which guys shave their heads -- in Pitch Black, Riddick (Vin Diesel) also spends one scene doing so, at one point explaining that the curvy chunk o' steel he uses is not a weapon, but a personal grooming appliance. Or something.
The scene in Desperado with Danny Trejo and the throwing knives is one of the only ones I remember from that movie. I also liked that crazy butler with the retractable wrist blades from Hudson Hawk (yes, I liked that movie, leave me alone). The psychotic Russian assassin in episodes 2&3 of Gunsmith Cats uses some pretty interesting ballistic knives.
In Lock, Stock, & 2 Smoking Barrels, Soap (Dexter Fletcher) produces a roll of fixed blades, which he displays to Eddie (Nick Moran) in the bar. Eddie's reaction is more or less what you'd expect. In another Guy Ritchie film, Snatch, Boris the Blade (Rade Serbedzija) uses a big fixed blade to chop off a dead guy's hand. There are a couple of Japanese-looking swords that emerge as well -- Bullet-Tooth Tony (Vinnie Jones) and Errol (Andy Beckwith) brandish them at several points during the movie. A sword also makes a brief appearance in The Big Lebowski (during that movie's hysterical confrontation between the protagonists and the nihilists).
As long as I'm veering off-topic and talking about swords, that part in every episode of "Abarenbo Shogun" where Yoshimune (Ken Matsudaira) does that dramatic "I'm turning my blade around" thing with his sword and starts cutting people up instead of smacking them around. Anybody know if that show is available on DVD? Also, the fight scene in the dojo during Crouching Tiger, Hidden Dragon. 'Nuff said, really.
