Mr. Echols, I would assume with your advanced age you would know the appropriate steps to take to have this issue resolved. If it is indeed a heat treat issue they would replace it free of charge, period. Are you saying you did pry with the knife and this how you noticed it bent? If it is just an opinion that it is not properly heat treated or whatever conclusion you have come to then obviously they will not replace it for free. If you have the experience you say you do which I do not doubt, you should have nothing to loose. If it is just lofty expectations, they will send it back to you and you are out the $5 plus change for the initial shipment.
Respectively, if I have a problem with someone's product, I personally would be sure to express my concern directly to them, not ask a friend or gentleman on the forums to do so for me. Reason being, how can they make it right if you don't give them the opportunity? If someone purchased a knife from you and it had heat treat problems (would bend or not keep an edge) would you rather have them contact you to fix the problem or have them make a thread stating they have a problem but aren't asking you to fix it just stating there is a problem with Echols Made Knives?
If you still wish to keep it as a display for your trade shows, I respect that. I however would urge you to let them inspect the knife so they may address whatever problem there may or may not be.
Best to you and yours this holiday season, respectively.
