Case can be hit or miss. Tragic for an old name in the cutlery world, but those times have passed. I've had experience with both, but Victorinox is on a pedestal by itself for production line QA. And Victorinox customer service is second to none, except maybe Buck. The Case is not a bad knife, but thats it. The Victorinox pioneer is in a class by itself as a compact tool in the pocket that can deal with lots of those little emergencies that tend to happen when we're far away from our tool box back home or in the trunk of the car a ways off.
I have to admit to being very prejudiced for the SAK, as I've been lucky to have one in my pocket to fix things 'out there', to include a gunked up fishing reel out on the Florida Straits in a rented boat with rented fishing gear, a conked out Vespa motor scooter on a lonely dirt road in the middle of nowhere, and some minor repairs on a rented cabin on vacation on the Rogue River. In each occasion, just having the ability to deal with Phillips screws and being able to partly disassemble something to fiddle with it, got me going again.
A knife is just a knife. All it can do is cut. But a SAK is a pocket size bundle of solutions to those little lives problems.
