Just received a response to my tear-soaked email to Wusthof after a giant cauliflower did for my favourite kitchen knife:

“All Wusthof items carry a limited lifetime warranty….Please note we do not cover returns for knives that have opened cans, pruned hedges or those that have not been used for their general suited purpose.”

‘opened cans, pruned hedges’ is excellent! Good to see humanity beginning to sprout in communication between companies and their customers.
