The 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.

Puma 6356 Original Bowie - A Unique Collector's Knife

The Puma 12 6356 is a remarkable vintage hunting knife known for its sturdiness, quality workmanship and excellent durability. Made in Germany from Pumaster steel, a high-performance alloy steel, this knife offers an ideal combination of hardness, wear resistance, and reliability. Pumaster approaches the performance of modern steels such as D2, with a similar composition that includes good carbon and chromium content. Although it does not reach the hardness of modern ultra-high performance steels, Pumaster is still able to maintain an exceptional edge over the long term, showing superior corrosion resistance compared to pure carbon steels such as 1095 or C75.

With a blade measuring nearly 10 inches long and an overall length of more than 15 inches, the Puma 12 6356 is an imposing knife that does not go unnoticed. Its nickel silver through-guard and rosewood handle give the knife a sophisticated look, while the quality of its craftsmanship ensures durable performance. 

This specimen, which appears to have never been used, is in excellent condition and is complete with its original box and leather sheath - special feature of the latter is that it is still marked “Western Germany,” which dates it pre-1986.

It is an ideal choice for any collector. Not only a high-quality hunting knife, but a true collector's item for fans of vintage Puma items.

The Moros is an excellent choice for field use or tactical applications. This well-balanced blade is the perfect blend of size and performance. Light enough to carry without discomfort but sturdy enough to tackle various daily tasks. The tip profile is flat with a tapered upper edge, ensuring excellent cutting performance with good penetration strength. The full tang and handle of the Moros provide a neutral balance, making it light in hand. The ergonomic and textured Micarta canvas handle offers a comfortable and secure grip, both dry and wet.

Notes: Design by Brad Zinker

While we've seen plenty of Boker products over the years, resourceful knife makers continue to find ways to surprise us. For example, Brad Zinker from Florida with his Urban Trapper, one of the thinnest profile titanium framelocks we've ever experienced. With just 8mm grip thickness (without clip), the term "slim" only inadequately describes the Urban Trapper for its usable size.

The large holes and titanium transform the Urban Trapper into a real featherweight of just 48 g that can be carried extremely comfortably both in a suit pocket and in light summer trousers. Considering the overall minimalist design of the knife, the size of the flipper is equally reserved.

When used, it still impresses with its outstanding functionality and reliably opens the blade on VG-10 ball bearings. The blade shape of this classic trapper pocket knife, widely distributed in the United States and worn for many years by Brad Zinker, was the inspiration for this unusual piece.
