I have all Wustof knives. I love them and keep them very sharp. The thing I love about them is if they are damaged, Wustof will replace them.
The investment made 30 years ago is the last time I've invested in knives. Recently, a paring knife broke in half at the blade. I returned it to them and they sent me a credit. I was able to purchase 2 new paring knives from its website to replace the one that I broke. I selected the replacements from the sale portion of the site.
