A lot of European knife companies made the mistake of putting these awful laminate wood handles on knives in the 70s and 80’s. I see a lot of these. This is a nice 10 inch chef. I assume it is a Wusthof. They claim to have stopped using this material 30 years ago and offer no warranty on it. New knives use a laminate wood called Pakka wood, I assume they have come a long way in resin technology since then. This kind of damage is a reminder never put knives in the dishwasher.
