I've got a victorinox that I've had for almost 20 years. I got it in school, and it lasted several years with almost 50lbs of books in it (yes, really. It was a private school).
One strap gave way in the first year, but my mom restitched it and everything else has held since. Only other people I have is that it smells kinda funky because I can't figure out how to wash it.
