I have seen this knife and reported it ... several times. Unfortunately, there isn't too much recourse. On the off chance an eBay or Amazon actually does respond to a trademark or patent violation the offender generally just opens up another account with a different username. We don't do business directly with Amazon or eBay, which does not put us very high on their policing priority list. The best step we can take is to educate on what is a legitimate KA-BAR. We have found that often generic or "K-BAR" style knives being sold alongside legitimate KA-BARs tend to push KA-BAR sales. We receive very few returns as a result of defects - unfortunately, many knives we do see come back to us are knock offs from an unsuspecting buyer.
