Hi,

Zero tolerance knives are really good knives, the liners locks from ZT is quite good. I own a ZT O300, and he has a very nice handle, when the knife is open, it give you an impression of thoughness and strengh, the blade and the handle become one. But the S30V Steel used by ZT, is very brittle compared to SR101 or Infi from Scrapyard knives, it made a little weak. The blade lost easily her sharp. I've never tested EMerson, are they good folder?
