Well, not really. But Victorinox, makers of the popular swiss army knives, has introduced a new model that incorporates a USB flash memory module. I’ve kept a swiss army knife on my keychain for years and I would actually consider this, though the asking price (roughly $90 for a 64MB model) is too steep. If they get the price down to a reasonable range, I would replace the one on my keychain in a heartbeat.
