Ordered a flat ground AR but when I opened the box, low and behold a hollow ground GB #54. I called T.A.D. to see if there was a mistake and if I needed to send the knife back. The guys at T.A.D. said the mistake was theirs and I could keep the knife if I wanted to. That's customer service to the highest order. Now I will only buy striders from T.A.D. and I still need to get the flat ground AR.
