Mate, are you are sounding like a 16yo girl who can't decide what panties she is going to wear to the party. That have offered a more than reasonable fix for your issues and it just seems as you are convincing YOURSELF that there is an issue with what they propose. Kinives are shipped back and forward across the US day in and day out with, in reality, very few problems...some are even shipped across the world without issue

. Pack it properly, include a note you don't want the blade touched (tape the blade if it makes you feel better) and send it back. To say that their approach is somehow wrong at this point is only reflecting badly on you not them my friend.
