Responding to the OP and original post...
One thing I have seen, is that TOPS attracts people who will beat the snot out of a knife.
And TOPS knives have had the snot beat out of them, repeatedly, repeatedly... [And I repeated 'repeatedly' on purpose]
So, if there existed a systemic issue, we would have heard about it. And no such out-cry has risen.....
TOPS makes a fine knife, and tough. Find a model you like and use it.
I seriously doubt you will have a failure.
But, if lightning should somehow strike you, TOPS will take care of you, of that I am certain.
Best,
Marion
