0,00 €Kubey Calyce Yellow Ultem Folding Knife, Blackwashed 14C28N (KU901Z)
The Kubey Calyce KU901Z is a distinctive variant of the Calyce model, combining a Sandvik 14C28N steel blade with a dark blackwashed finish and a yellow Ultem handle. The contrasting design features a Liner Lock, ceramic ball bearings, and Black PVD hardware.
The 83.00 mm blade has a Drop Point profile and a flat grind. Manual opening is facilitated by a flipper and ambidextrous thumb studs.
Sandvik 14C28N and Vacuum-Cryogenic Treatment
The blade is made of Sandvik 14C28N steel, hardened to 60–62 HRC. Vacuum hardening combined with cryogenic treatment promotes high hardness, wear resistance, and stable steel performance during regular use.
Drop Point, flat grind, and Blackwashed
The Drop Point profile offers versatile functionality and good tip control. The flat grind supports efficient cutting, while the blackwashed finish gives the blade a dark, rugged look.
Yellow Ultem, Liner Lock, and Black PVD Hardware
The handle is made of yellow Ultem, which creates a striking contrast with the dark blade. The design is complemented by black stainless steel spacer rings and Black PVD Hardware.
Ceramic ball bearings ensure smooth blade movement, while the Liner Lock secures the blade when fully opened. The steel clip can be mounted on the right or left side in a tip-up configuration.

Frequently Asked Questions
How do I care for Sandvik 14C28N steel?
It is recommended to clean the blade regularly and dry it thoroughly. 14C28N combines corrosion resistance with ease of sharpening, making it ideal for everyday use.
How do I sharpen the Kubey Calyce?

The recommended sharpening angle range is 15°–20°. This allows you to adjust the edge geometry to your preferred balance between cutting aggressiveness and blade durability.
How does the Liner Lock work?

It’s a good idea to regularly clean dust and fine debris from around the pivot. If necessary, you can use a small amount of a cleaner designed for knife mechanisms.
