In a worldstate whitch involves the reviving of cryonicly stored people, I would expect a weapon would be one of the last things on my list of things I would need. That is to say, a world which has sufficiently advanced technology, sufficient resorces, and so on to revive cryonicly stored people would not be a wolrd were civilisation has colapsed, not be a world were order has broken down, and in other words would be a world in which a weapon would be about as useful as a weapon is in a first world country today, which is to say, it would be not all that esential.
The Scenario: Our protagonist estimates that present-day cryonics has around a five percent chance of leading to a successful revival. Since that's better than the zero percent chance if he doesn't sign up, and he can afford it, he makes the necessary arrangements. As part of those arrangements, he receives a lockable file-cabinet drawer, in which he can put any desired mementos, knick-knacks, or other objects; and which will be protected as securely as his own cryo-preserved body. The drawer is around one and a half cubic feet: two feet deep, one foot wide, nine inches high.
The Question: What should he arrange to have placed in his drawer?
Some of the more obvious options:
* Long-term archival DVDs, such as M-Discs, containing as much of his personal computer's data as possible. With slimline jewel cases, around 400 such discs would fit, which could hold up to around 1.5 terabytes. (Secondary question: Which data to archive?)
* Objects of sentimental value
* Objects with present-day value: cash, gold coins, jewelry
* Objects with predicted future value: collectibles, small antiques
* In honor of previous seekers of immortality: a copy of the ancient Egyptian funerary text, the Book of Coming Forth By Day (aka the Book of the Dead).
* For the purely practical and/or munchkin approach: a weapon, such as a fighting knife or even a pistol
