I purchased a 16" Victorinox knife. It has a spot of untempered steel that cannot be sharpened. I sent it back to the company and was told it was out of warranty. The knife is like new. It cost me $10.00 plus shipping for them to look at it. Just want to warn people; they don't stand behind their product. I have used their knives in my meat business and never had a problem; but if you do it's your problem, not theirs. They don't stand behind what they sell. That is in my case.
