I've had Kraton and similar material knives for 35 years now. Not one has gone loose on me. Of course I have lots of micarta, leather and various
wood handles too. But in my opinion the Kraton handles offer two attractive features, one is that they are very maintenance free. A Kraton handled knife used
to dress game or fish need only be left in a bucket of freshwater. The second feature is that they are invariably lighter than their full width tang better handle material
versions. And wearing a fixed blade, weight does count sometimes. Kraton is affixed to the tang with epoxy so it;s not surprising that some do fail. But the numbers are
small. There are some folks who talk like Kraton melts in sunlight or something. Doesn't happen so easily or often.
