Kubey Whammy Knife Black Titanium, Satin 14C28N by Keanu Alfaro (KU474D)

Kubey Whammy Black Titanium Folding Knife, Satin 14C28N by Keanu Alfaro (KU474D)

The Kubey Whammy KU474D is a darker variant of Keanu Alfaro’s titanium folding knife, combining a satin-finished Sandvik 14C28N steel blade with a black-washed titanium handle. The gold-anodized pivot cap breaks up the dark color scheme and gives the model a distinctly unique character.

The 86.00 mm blade features a Wharncliffe profile and a flat grind. Manual opening is achieved using a flipper or 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 properties.

Wharncliffe, flat grind, and Satin

The Wharncliffe profile provides a long, straight cutting edge and excellent control during use. The flat grind ensures smooth cutting, while the satin finish on the blade creates a striking contrast with the dark handle.

Blackwashed Titanium, Frame Lock, and Gold Pivot

The handle is made of blackwashed titanium. The design is complemented by black stainless steel spacer rings, a titanium clip, and a gold-anodized pivot cap, which is a distinctive feature of this variant.

The blade operates on ceramic ball bearings, while the Frame Lock secures it in the open position. The titanium 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’s a good idea to clean the blade regularly and dry it thoroughly. 14C28N offers good corrosion resistance, but regular care helps preserve its performance and appearance.

How do I sharpen the Kubey Whammy?

The recommended sharpening angle range is 15°–20°. This allows you to adjust the edge geometry to your preferred balance between durability and cutting aggressiveness.

How does the Frame Lock work?

The Frame Lock uses a section of the titanium handle as a locking element. When the blade is opened, it slides behind the blade’s pommel and stabilizes the blade in the open position.

How do you maintain ceramic ball bearings?

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