Do you seriously believe that a 0.00000003% failure rate of an easily replaced, non-critical, $0.50 part calls for a redesign and replacement of tens if not hundreds of thousands of dollars worth of molds and possibly other equipment as well? Amazing.
Yes!
If it has happened to me and my son in law, its most likely happened to others. If it was a random break, no, but the same break in the exact same spot on three different SAK's that were all less than a few years old, is odd.
The very fact that the breaks were all the "new" thinner hollowed out scales is odd, to say the least. And the break was right along the 'hollow' edge on the back side scale.
The fact that you have to be careful with cellidor around certain solvents/cleaners used in the auto mechanic and machinist trade is odd.
The fact that certain bug repellents will start to dissolve cellidor is odd.
The fact that it was a blatant move on the part of Victorinox to save a penny or two by using less cellidor per SAK is more than odd.
YES, Victorinox needs to step up ands a better material than the cheap stuff they are now using. This isn't the 1940's and there are way better materials for just as cheap.
