I had to chime in. I've got a HALO 3, an Ultratech, and a Makora. Thing is very few people know what sharp really is. We all watch cooking shows and watch as they cut with precision and wonder why or 129.00 "pro" set in the kitchen doesn't do the same. Sharp is one of the things you pay for with microtech, scarey sharp. The spring in a halo won't punch through your hand but unlike any other otf... it will send you to the hospital for stitches. The Ultratech actually penitrates more than the others from just opening it, it with go threw a cardboard box or a towel. So, there is the truth.
