Cudeman Tundra (346-JN): the mirror-polished black Juma version for EDC and display
The Cudeman Tundra (346-JN) in its polished black Juma finish captures the idea of functional elegance, designed equally for everyday carry and for showing off in a collection. Conceived for anyone who needs a cutting tool that pairs an understated look with professional-grade performance, this folding knife stands out for its remarkable balance. Its design prioritises complete control on precision work, so every movement feels smooth and, above all, safe, whether in the city or out in the field.
What makes it special
- Sheep-foot blade: its profile delivers cutting control to the millimetre, ideal for clean, safe cuts while reducing the risk of accidental punctures.
- Solid lock: it features a heavy-duty back-lock system that keeps the blade fixed and stable under any working load.
- Take-apart build: the use of star screws and an Allen screw instead of rivets allows precise maintenance and provides a firm structure that prevents play over time.
- One-of-a-kind piece: the polished black Juma of the handle shows its own grain on every example, turning each knife into a unique object with a high-end polished finish.
Steel and edge
The heart of this knife is a blade made of Bohler N690Co steel, one of the most exclusive alloys in Cudeman's production. Hardened to 60/61 HRc, this alloy is renowned for its excellent edge retention and high resistance to corrosion. The hollow grind, together with a satin finish and polished bevels, delivers an almost surgical cutting ability that holds up even after long days of use. For a correct and risk-free resharpening, it is best to turn to a professional.
Construction and durability
Made entirely in the Cudeman workshops in Albacete, the solidity of the Tundra is obvious the moment you pick it up. With a 2.8 mm thick blade and a frame reinforced with quality bushings, this folding knife is ready for everyday carry (EDC). The polishing of the blade bevels goes beyond looks: it reveals the level of craftsmanship applied by hand to a professional cutting tool. To guarantee a solid structure and flawless behaviour over time, the blade is secured to the handle with an Allen screw and an internal brass bushing, a mechanism that ensures a precise, play-free fit while protecting the steel and the handle from wear caused by friction.
Handle and ergonomics
The polished black Juma handle offers an ergonomic grip and visual appeal that is hard to match. Juma is a high-density synthetic material valued for its durability and its good behaviour against temperature changes. Its 10.8 cm length lets you rest the whole hand on it, which translates into superior directional control and comfort that keeps fatigue at bay during repetitive tasks.
Versions and sheaths
Depending on whether it is destined for EDC or for adding shine to a display cabinet, the black Tundra is offered in two references:
- 346-JN: knife without sheath, designed for the most premium display.
- 346-JNF: knife with a full black sheath, in black and with black thread (sheath 636-N).
What to use it for
- Everyday carry (EDC): its sheep-foot tip is perfect for opening parcels, cutting fibrous materials or handling office tasks with maximum precision.
- Outdoors: a trusted ally for hiking or camping, where you need a forceful cut in a compact, lightweight tool.
- Collection: the blend of high-end steel with polished black Juma turns it into an object coveted by fans of semi-handcrafted Spanish cutlery.
Care and maintenance
- To preserve the shine of the black Juma, keep the piece in a dry place and never wet it under the tap.
- After each use, wipe the blade with a microfibre cloth to remove fingerprints or moisture and keep the polished bevels immaculate.
- Every now and then, place a drop of light oil on the pivot so that the deployment and the back-lock work with total smoothness.
- Check the tightness of the star screws from time to time to maintain optimal structural tension.
The Cudeman Tundra (346-JN) wraps the reliability of N690Co steel in the deep, dark elegance of mirror-polished black Juma. Available at Navajeria with shipping across mainland Spain.
