He had 2 that I saw. One I held, and the other I only saw for about 1 second.
He had a small/medium knife that I did not recognize (roughly Chaparral size) with a new prototype lock that they had just built for testing (I felt extremely lucky that he handed it to me and let me check out how it works). I believe he said it's a new lock Eric came up with. It was pretty sweet, and worked great. I don't want to describe it though because they haven't released it, so I figure I should leave it up to Sal to discuss it or not.
The other one I only glanced at for a second when he flashed it while we were talking about the difficulty of traveling with knives. It was very small like a Manbug or possibly a Grasshopper or something similar.
