* Inspected and Certified by our in-house laboratoryThe Zero Tolerance 0100 is one of the first knives produced by Zero Tolerance, the premium division of Kai USA, which was launched in 2006 to develop professional tools for military personnel, law enforcement, and first responders. The 0100 model was, in fact, one of the first three fixed-blade knives in the original lineup, alongside the 0121 and 0150 models.
The design bears the unmistakable stylistic signature of Ken Onion, the renowned American designer already responsible for numerous successes at Kershaw. The distinctive “S”-curved blade offers an unusual combination of cutting ability, power, and precision, making the ZT0100 suitable for both tactical applications and the most demanding outdoor use.
For its construction, Zero Tolerance chose CPM 3V, a steel then considered cutting-edge for its strength and impact resistance, paired with a tungsten DLC coating and three-dimensionally machined G-10 scales. This combination helped solidify the brand’s early reputation as a manufacturer of “overbuilt” knives, designed without compromise for field use.
Today, the ZT 0100 is a discontinued model particularly prized by collectors, as it is considered one of the knives that helped define the Zero Tolerance brand’s identity in its early years.

Notes: designed by Paolo Bozzo
Dear Friend,
I am Paolo Bozzo and many times ml have found myself in unpleasant, pericolase and difficult situations. Designing a knife and testing it just a few afternoons in the woods is quite different than designing one trying to solve all those survival problems I have encountered in the last 25 years, both In ltaly and abroad. Mud, water, dirt, grease, blood, fatigue, night use, weak hand, limited space, trajectories, physical deficits, heat, cold, transportation, speed and much, much more...these are just some of the tests a good design must pass.
Here are some of the reasons for the WF4 Rough Wolf design.
1. Balance: it is fondamenlal that the center of gravity is shifted forward. beyond the heel, such that it decreases, i.e., saves energy when delivering the blow. one must always have the feeling that the knife falls forward.
2. Beating mass: 65% of the weight of the whole knife is between the first and second 3rd of the blade, giving maximum beating capacity in penetrating.
3. Cutting edge: due to the main core in the shape of an esse. the cutting edge is lower than the fingers of the handle, with the result that in the dynamics of the fendenle and biomechanics of the arm, the force expressed is never attenuated; especially never before the impact of the same on the object to be cut.
4. Blade height: compared to other blades, it has a significantly higher ability to dig holes.
s. Handling: excellent the ability to use the Wp4 for both coarse and precision work, this thanks to the ability to put the hand before the guard, giving absolute mastery of the blade despite its size. This is thanks to the large heel where the index finger can be inserted and the convenient thumb rest. It is also possible to do this while wearing tactical gloves.
6. Back: the inclination is reversed for 2 reasons; 1st to give forward beating mass, 2nd not to stress the wrist during use as chopping, a normal knife arrives at an angle on the object, devastating the point of impact being slight in thickness. This can only be avoided by straining the thumb-side wrist to tilt so that the back of the knife falls perpendicular on the object. The wp4 does not have this problem; it does not stress the wrist because the back of the blade already falls perpendicular to the object to be beaten.
7. Bevel: it is very high, has impressive penetration capacity.
8. Milling cutter: 5 millings placed on the blade plane for holding the knife with two hands when handling animal hides or for special uses during bushcrafting.
9. Grip: it is designed to decrease the possibility of losing the blade and avoid opening of the phalanges during pmlong use or in situations of prolonged physical deficit. Improved, anti-slip grip with internally concave Gauntlets to accommodate a Micro SurvivalKit.
As for the scabbard, I believe it is as important as the blade. I proceeded to design it and recommend its qualities; the main feature I wanted to put in designing it was the multi-positioning of the same: in particular, placing it at will on one's body or equipment facilitates the possibility of use.
This quality is particularly appreciated by military personnel, who are known to have special technical and logistical needs. For this purpose we have used in addition to Kydex the Keyblock closure, as well as the many holes along the perimeter; also safe for airdrop it has the possibility of use and positioning by both Right and Left handed operators.
