I'm heading off on tour soon and was thinking a Swiss army knife of some sort would be useful. My work are also asking what to get me for a leaving present but I've got virtually everything I need so I thought this would be a good thing for them to get me. Which one would you suggest? I think I'll need a tin opener and corkscrew as a minimum but there are so many options! I already have a bike multitool with screwdrivers and allen keys.
