Cudeman Tundra (346-JR): A revolution in your hands; Avant-garde and unprecedented design, dazzling mirror-polished juma and manufactured with the most premium steel in our warehouse

The Cudeman Tundra (346-JR) redefines the concept of an everyday carry (EDC) knife by fusing professional blade geometry with vibrant, modern, and sophisticated aesthetics. Manufactured for those who are not content with standard tools, this model offers impeccable mechanical security with a back-lock system and exceptional cutting capability, becoming the perfect ally to elegantly solve any challenge that arises during the day, whether in urban environments or nature outings. A unique piece that will add that missing touch to your collection display case.

Why this Cudeman is for you

  • Sheep-foot Geometry: Its dropped tip provides superior cutting control and greater safety when working near delicate surfaces, preventing accidental punctures.
  • Exclusive aesthetics: The use of polished Red Juma ensures that your knife is a unique piece in the world, with an unrepeatable grain pattern that projects personality and status.
  • Absolute locking security: The back-lock system firmly anchors the blade, allowing you to apply force with the peace of mind that the tool will not fail, causing accidental cuts.
  • Professional technical adjustment: The star screw fastening allows for precise maintenance and ensures that the structure remains solid and free of play for years.

Steel and blade performance

At the heart of the Tundra is Böhler N690Co steel, a high-end alloy with a hardness of 60/61 HRc. This steel stands out for its extraordinary edge retention and outstanding corrosion resistance thanks to the cobalt content. Its hollow grind and satin finish with polished edges offer a surgical and fluid cut. Due to the high hardness of its steel, we recommend seeking a professional to maintain its natural geometry when re-sharpening.

Construction and resistance

Manufactured entirely in our facilities in Albacete, the Tundra presents a structural solidity that is perceived from the first deployment. Its 2.8 mm thick blade offers the necessary robustness for real utility tasks, while the polished edges demonstrate a superior level of artisanal detail. Although it is an extremely resistant tool, its design is optimized for precision cutting and its use for extreme side prying should be avoided to preserve the integrity of the axis. The blade is attached to the handle by means of a pivot axis system with an Allen screw, equipped with an inner bushing and brass washers. This high-precision mechanical solution minimizes friction, guaranteeing a millimeter-perfect adjustment, impeccable blade centering, and unparalleled opening smoothness.

Handle and control in real conditions

The polished red juma handle offers fluid ergonomics and a sophisticated feel that naturally adapts to the palm of the hand. Juma is a high-tech synthetic material that stands out for its durability and resistance to the elements. Its 10.8 cm length ensures a firm and balanced grip, allowing total control over the cutting direction without generating fatigue points, even in prolonged use.

Sheath and portability

The Cudeman Tundra finds its place both in the hands of the purist collector, who acquires the bare tool to admire its craftsmanship in a display case, and in the pocket of the more pragmatic user, who relies on it as their inseparable everyday carry (EDC) tool. That's why at Cudeman we offer you these two options:

  • 346-JR: Knife without sheath
  • 346-JRF: Knife with black sheath with red stitching to match its juma (sheath 636-NR)

Use scenarios

  • Precision cutting: Ideal for utility tasks that require millimeter control thanks to its Sheep-foot tip.
  • Daily use with distinction: A compact, striking, and elegant tool that solves everyday needs, providing a touch of technical exclusivity.
  • Modern collecting: An indispensable piece for those who value the application of innovative materials in traditional cutlery manufactured in Albacete.

Care and maintenance

  • To maintain the vibrancy and shine of the polished red juma, it is recommended to store the piece in a dry place and avoid moistening it or submerging it under the tap.
  • After use, clean the blade with a microfiber cloth to keep the satin finish and polished edges free of fingerprints or residue.
  • Periodically apply a drop of light oil to the axis and the back-lock mechanism to ensure smooth opening and prevent seizing.
  • Occasionally check the adjustment of the star screws to ensure that the structural tension is always optimal for your hand.

The Cudeman Tundra (346-JR) is the perfect meeting of material innovation and modern design; a jewel to display in your showcase or a perfect EDC for your daily life, a reliable tool made to stand out and last.

Frequently Asked Questions

Popular questions from our customers


  • All Cudeman products are designed and manufactured entirely in Albacete, Spain. The brand has over 38 years of experience, combining traditional Albacete cutlery craftsmanship with the latest technologies (such as laser cutting and CNC machining). When you buy a Cudeman, you are acquiring a product with a designation of origin that guarantees quality and know-how.

  • 1. Premium Steels: Böhler N695 / N690Co

    These are the benchmark steels in our high-end range. Böhler is synonymous with purity and Austrian technology.

    • Properties: High hardness (58/61 HRC), excellent corrosion resistance, and superior edge retention thanks to their high chromium and cobalt content (in the case of N690Co).
    • Ideal use: Extreme survival and bushcraft knives (like the famous MT series or the Green Beret), designed to withstand intensive use without losing their edge.

    2. The Gold Standard: Molybdenum Vanadium (MoVa)

    The quintessential steel of Spanish cutlery, valued for its great structural balance.

    • Properties: Reaches a hardness of 54/56 HRC. Its greatest virtue is its toughness (impact resistance) and ease of re-sharpening in the field, even with basic stones.
    • Ideal use: Hunting, finishing, and general-purpose knives. It's the all-terrain steel that never fails in hunting activities.

    3. Swedish Precision: Sandvik 12C27 / 14C28N

    Very fine-grained stainless steels produced in Sweden, ideal for those seeking a "laser" edge.

    • Properties: 14C28N, in particular, offers a masterful balance between hardness (57/59 HRC) and corrosion resistance. It allows for very sharp edges that are resistant to micro-fractures.
    • Ideal use: High-end folding knives (EDC), adventure cutlery, and pieces that require a clean and precise cut.

    4. Tactical Resistance: 420 Stainless Steel

    A very elastic steel resistant to external agents, used in specific high-impact pieces.

    • Properties: Lower hardness than the previous ones (50/53 HRC), which makes it extremely resistant to breakage under torsion or impact. It is virtually immune to oxidation.
    • Ideal use: Throwing knives, diving tools, and low-maintenance tactical cutlery.
  • A high-quality knife is a tool for life, but its longevity depends on maintenance, especially when combining technical steels with natural materials in the handles.

    1. Cleaning and Drying (Crucial for natural materials)

    • Hand washing: Clean the blade and handle with warm water and neutral soap. Never use a dishwasher, as extreme heat and chemical detergents are lethal to steel and wood.
    • Attention to porosity: If your Cudeman has wood, antler, or bone scales, avoid submerging them or leaving them to soak. These materials are porous; moisture can cause them to swell, crack, or separate from the knife's chassis.
    • Immediate drying: Dry the entire piece with a soft cloth immediately after washing. Make sure no moisture remains in the rivet area or joints.

    2. Lubrication and Protection

    • The Blade: If you are going to store the knife, apply a thin layer of mineral oil (or camellia oil) to the steel. This creates a hydrophobic barrier against environmental moisture, which is vital even for stainless steels.
    • The Handle: For natural wood handles, it is advisable to occasionally apply a little linseed oil or beeswax. This nourishes the material, seals the pores, and prevents it from drying out or accidentally absorbing water.

    3. Storage and Leather Sheaths

    • Leather is organic: Leather sheaths are hygroscopic (they absorb moisture). Do not store the knife inside its sheath for prolonged periods of inactivity, as the leather's tanning and retained moisture can cause oxidation pitting on the steel.
    • Sheath maintenance: Hydrate the leather regularly with horse grease or specific creams. A flexible and nourished sheath better protects your tool and prevents the leather from cracking over time.

    Golden rule: A Cudeman knife is not ruined by use, but by neglect. Clean, dry, and store separately if you are not going to use it soon.

  • Cudeman offers a lifetime warranty against any manufacturing or material defects.

    Important note: The warranty does not cover natural wear and tear from use, nor damage caused by misuse of the tool (such as extreme batoning with models not designed for it, throwing the knife, or using it as a lever).
    Items made with natural materials (woods, antlers) or special resins (Juma) may show inherent differences in grain and color compared to the photographs. These aesthetic variations do not constitute a manufacturing defect and are therefore not covered by the warranty or eligible for return.
