ZT's 0301 incorporates Ken Onion's SpeedSafe, which is essentially an assisted-opening system. The Onion design uses a spring system and a small flipper on the blade. When pushed, the blade opens quickly. If the SpeedSafe fails, the blade can still be operated like any other folding knife. When the knife is opened, the SpeedSafe flipper becomes a blade guard that prevents your hand from sliding onto the blade when cutting.
Measuring 4.25 inches and made of S30V stainless steel, the blade is itself impressive. S30V stainless is fairly corrosion resistant, and it can hold and take a sharp edge. A drop point hollow grind further strengthens the blade. This style has a strong point and is well suited for a wide variety of uses. In keeping with the 0301's roots from Strider, the blade is tiger striped with Tungsten DLC. This enhances the blade's corrosion resistance and gives it a cool look, to boot.
To bring all these good parts together into a usable knife, Zero Tolerance uses titanium and G10 for the frame and grips. The titanium frame and liner lock help reduce the knife's weight and increase its durability. G10 is used for one grip panel to give the knife a pleasing look and to help reduce the knife's cost. Both grip panels are drilled and tapped at both ends so the user can choose where to put the clip. The scallop effect on both the titanium and G10 panels gives the operator a solid purchase on the knife and cool aesthetics.
To further enhance the user's purchase on the knife, the frame has two sets of horizontal serrations. One set is at the rear of the blade where your thumb would rest, while the other is positioned at the rear curve of the knife. Both serve their purpose in dry or the wettest of conditions.
My first impression of the Zero Tolerance 0301 was that it was just too big. But after carrying it and using it, I realized that size is part of this knife's functionality. I wouldn't wear it with lightweight pants, but most uniform and BDU pants are not lightweight, and the 0301 carries well clipped to a pocket.
