Emerson has no way of explaining every single act or variation of an act that can cause warranty violation, so its far easier to have a blanket statement such as 'no modifications". I personally don't blame them. Can you imagine trying to service a knife that has been submerged in paint and every part has now been gummed up or at the very least the tolerances have been changed? Now I know that is a bit of an exaggeration, and not what was done in this case, but it would be hard to tell the consumer just how much painting can be done to a knife before you have voided the warranty. Most manufacturers will not work on modified knives. Also, the warranty information is on their site and from what I remember is not hard to find. It has also been discussed many times before. If you no longer wish to own the knife because of this policy, you shouldn't have a problem selling it.
