I can understand your irritation. However, the person you should be talking to is the exhibitor you went to see. An email or phoine call in advance would have also helped. It has been a long time since I was at Blade, but this has happened many times. There was a big name and high priced dealer directly behind me. He sold the four knives he had brough in a few hours .. for a total of well over $50K. He left his table and put out his photos and contact info .. and I didn't see him again the rest of the weekend. When we packed and left Sunday afternoon the stuff was still on the table. I have seen him at other shows where he comes and puts a knife in the judging, picks i up after the judges are done looking them over ... and leaves. He never picks up his trophy or shows up again that weekend. An email to the promoters would help future issues, but I would aslo check thatnthe seller didn't have a family emergency that he had to return for.
