  3. Zero Tolerance - ZT0100 by Ken Onion - Black DLC CPM-3V & Black G10 - PRIVATE COLLECTION - knife

    KNIFE FROM A PRIVATE COLLECTION
    * Origin: Previously purchased knife from a private collection
    * Condition: 2008 model, overall in excellent condition
    * Commercial Availability: Discontinued
    * Sharpness: Factory-sharpened, could be improved
    * Blade Condition: Minor cosmetic marks on the DLC finish due to age

    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.

    Idun is a deity in Norse mythology, known as the keeper of the apples of eternal youth. These magical apples grant immortality to the gods who consume them, keeping them eternally young and vigorous. Idun plays a crucial role in the Norse pantheon, as without her apples, the gods would begin to age. A famous myth tells of how Loki kidnapped her under the order of the giant Thjazi, causing the gods to age rapidly until her release. Her connection to youth and vitality makes her a central figure in Norse mythology.

    Fallkniven Three Kronor TK1

    The “Three Kronor” line blends the latest martensitic technologies with the ancient roots of the Swedish royal family.
    In fact, these knives are the only ones that can boast the royal symbol of three crowns placed on the blade and on the beautiful wooden box that contains the knife and sheath.
    The rolled steel used is currently one of the best industrial steels on the market and is composed of an inner sheet of SGPS from powder, a steel already used for the U2 model, at 62HRC coupled with two outer sheaths of VG2. The knives thus reveal exceptional cutting, penetration and edge-holding qualities.

    Blade: Three-layer rolled 3G steel (VG2 and SGPS “Super Gold Powder Stainless Steel” at 62 HRC)
    Handle: Cocobolo wood
    Blade length: 100 mm.
    Blade thickness: 4.5 mm.
    Total length: 215 mm.
    Weight: 145 g.
    Sheath: Black, leather
