I am a monk of the Abbey of Gethsemani. I thought that when I entered monastic life, I would have to give up my lifelong love of movies. However, I have been asked to produce short films depicting life at the monastery.
Yeah, in the opening shots of Miller's Crossing (still my favourite Coen Br's movie), a close-up on a glass with the ice cubes hitting it and the whiskey being poured in are perfect, just as off-camera the great Jon Polito (should have an Oscar for his performance here) says, "Ethics." Fantastic opening for a movie. These guys really have everything nailed down. The best directors working today.
The problem with any regular screwdriver blade (and hence all the alternate tools mentioned in the comments) is that it doesn't fit the slot. I have a swiss army knife which I use most of the time, but some of my screws are showing signs of wear. I almost bought the filmtools screwdriver just for the blade, but it was just too expensive. I will be getting this one shortly. Two, actually. One for the keychain, one for the bag.
