Cudeman Tundra (346-JR): an EDC folding knife in mirror-polished red juma and premium steel
The Cudeman Tundra (346-JR) rethinks what an everyday-carry (EDC) folding knife can be, pairing a professional cutting blade with a bold, contemporary finish. Made for those after something different from conventional tools, it combines a reliable back-lock mechanism with serious cutting power, handling daily tasks with ease both in the city and outdoors. It is also a knife with real character, adding the spark a collector's display case often lacks.
What makes it special
- Sheep-foot blade: the dropped point improves cutting control and reduces the risk of accidental punctures when working close to surfaces you want to protect.
- One-of-a-kind finish: the polished red juma gives every unit a unique grain that cannot be reproduced and that brings genuine personality.
- Secure lock: the back-lock holds the blade firmly in place, letting you apply force without fear of the edge folding unexpectedly.
- Easy maintenance: the Torx (star) screw assembly makes fine adjustment simple and keeps the knife solid and play-free over time.
Steel and edge
At the heart of the Tundra is Böhler N690Co steel, a high-end alloy hardened to 60/61 HRc. Its cobalt content delivers excellent edge retention together with very high corrosion resistance. The hollow grind and satin finish with polished bevels produce a clean, precise cut. Given the high hardness, it is best to leave resharpening to a professional so as not to alter the blade's original geometry.
Build and toughness
Made entirely by Cudeman at its workshops in Albacete, the Tundra feels solid from the very first opening. The 2.8 mm blade thickness gives it the body it needs for real use, while the polished bevels reveal careful, artisanal finishing. Despite its strength, it is designed for precision cutting, so avoid using it for extreme lateral prying in order to protect the pivot. The blade joins the handle through a pivot-axle system with an Allen screw, inner bushing and brass washers; this precision mechanism reduces friction and ensures a millimetric fit, perfect blade centring and a remarkably smooth opening.
Handle and ergonomics
The polished red juma handle has a refined feel that settles naturally into the palm. Juma is a latest-generation synthetic material valued for its durability and how well it withstands the elements. At 10.8 cm long, it offers a secure, balanced grip that keeps control of the cutting direction without fatigue, even during prolonged use.
Versions and references
The Cudeman Tundra suits both the collector, who prefers it bare to show off its craftsmanship, and the practical user who carries it every day (EDC). That is why it comes in two references:
- 346-JR: knife without sheath.
- 346-JRF: knife with a black sheath featuring red stitching to match the juma (sheath 636-NR).
When it fits
- Precision cutting: ideal for tasks that demand millimetric control, thanks to its sheep-foot point.
- Everyday carry with style: compact and eye-catching, it covers daily needs with a touch of technical exclusivity.
- Modern collecting: a compelling piece for anyone who appreciates innovative materials applied to the traditional cutlery of Albacete.
Care and maintenance
- To preserve the shine and vividness of the polished red juma, store the knife in a dry place and avoid wetting it or running it under the tap.
- After each use, wipe the blade with a microfibre cloth so the satin finish and polished bevels stay free of fingerprints and residue.
- From time to time, add a drop of fine oil to the pivot and the back-lock mechanism so the opening stays smooth and does not seize.
- Periodically check the tightness of the star screws so the assembly keeps its proper tension.
The Cudeman Tundra (346-JR) brings together innovative materials and modern design in a single knife: it looks great in a display case and works just as well as a trusty EDC companion. Available at Navajería with shipping across mainland Spain.
