More a coincidental progression than extensive planning. The only changes i made purely for looks is changing to that clear cased Tritium glow tag (never liked the look of the green plastic Nite one) and i changed the captive bit on the Nibble to a weird bluey silvery coloured one instead of the rusted up one that is pictured. The LD01 i never intended to buy and put on my keychain, but i prefer the stainless look over the anodised look of the normal LD01 which is why i got that model. I also carry one of these as well now which also follows the theme but i had one back in 2006 and only just got around to getting another (its super solid and one of the few USB drives id trust on a keychain like mine). Its a great little thing. I also worked out a technique for opening it one handed for emergencies (when loose, its easy to do when held in the keychain obv) which is a solid improvement over the Vic Rambler it (and the Nibble) replaced/upgraded.
