RN, If you are refering to the little knife with the HK, it's called a Poliwog I think. IF you are referring to the one above the 1911 A1 45, I have no idea what it is called.
You are correct, that is a Poliwog under an XD .45 compact with a 13 shot mag and cover sleeve. The Syderco above the 1911 is a carbon fiber handle Tim Zowada design and it indeed has a false edge. It is a very cool knife and I do like it. <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />
