I noticed on the new Victorinox Rescue, several of the tools are advertised as being beefed up considerably, including the wedge/screwdriver and the phillips - and the locking mechinism works differently on the Rescue than on any other locking blade victorinox multi-knives. I think there are two tools that lock on the Rescue - the main blade and the wedge. And two of the other tools (the disk blade for cutting auto window glass and the window breaker, are replacable and spares are readily available. I think this is the first tool to have a replacable disk blade, but I specultate that Victorinox is going to expand the concept as to the wood saw and other tools that wear out quckly if used a lot, or in emergency circumstances. This knife is really a departure from all previous Victorinox designs - and it's sale is limited or restricted in the US - but readily availbe in Europe to citizes of the USA - at this time. UnFortnately, customs can be a problem during the FedEx shipping process - and could delay the receipt of this tool, even if it is sent by FedEx. Becuase of the extreme nature of the tools, I'll bet european civilians are not allowed to own them in many of the european countries ; & sales are limited to fire, rescue and police departments -
