KNIFE PREVIOUSLY PURCHASED, FROM A PRIVATE COLLECTION
* Provenance: Acquired from a private individual, previously purchased
* Condition: Overall in excellent condition; shows no signs of actual use. It does, however, have the typical scuff marks caused by inserting and removing the sheath, which inevitably abrades the satin finish of the blade; these marks are superficial, uniform, and characteristic of this particular knife model. The sheath is in excellent condition, with minimal signs of abrasion and no breaks or sagging. It comes with an additional nylon pocket with Velcro that contains the original vintage oil-lubricated compass.
* Commercial availability: Discontinued
* Sharpness: Factory-sharpened, but could be improved. Not re-sharpened to preserve the product’s original appearance.
* Marks on the blade: Several superficial abrasion marks left by the sheath, typical of this particular knife model
* Marks on the handle: A few barely noticeable signs of age
* Box: -
* Sheath: Present, in excellent condition, with an additional nylon pocket containing the original period oil-filled compass

The most distinctive—and patented—feature of the Buckmaster Buck 184 is the presence of two removable, screw-mounted harpoons, or hooks. Their primary function is to provide an anchor point: the knife can, in fact, be used as a sort of throwing hook by attaching a rope to the ring on the pommel. The manufacturer claimed the grappling hooks had a holding capacity of up to 600 pounds.

In the case of the Navy SEALs, the requirement was for a knife that could also be used underwater and, if necessary, allow for the anchoring of equipment or vehicles to a submerged anchor point. This specific requirement contributed to the choice of an all-steel construction, designed to offer strength and durability even under harsh underwater operating conditions.

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.
