The blade of the Limited Edition Mars Valley FatCarbon CRJB Mini Pyrite is made from premium CPM-S90V stainless steel for excellent edge retention and corrosion resistance. The FatCarbon and titanium handles are comfortable to hold and fit well in the hand thanks to its gentle curve and bevel designed to accommodate the index finger. The Mini Pyrite uses a combination of its button lock mechanism with ceramic ball bearings in the pivot to make this knife quick to deploy and always ready in hand. The smooth action allows the blade to be flicked open with one hand with a press of the button lock or a flick of the thumb slot.
