Kubey has quietly expanded its budget-oriented Ceyx line with a fully blacked-out edition. The Ceyx KU335D lists at $50 and wraps a darkwashed D2 tanto blade in black G10, aiming squarely at buyers who want an aggressive-looking working folder without stretching past the fifty-dollar mark. It is now listed on the company's official store.
A Deliberately Stealthy Package
The blackout theme is consistent from tip to clip. The 2.95-inch blade carries a darkwashed finish over a flat grind, the handle scales are black G10, and even the stainless pocket clip and pivot hardware follow the same muted palette. The tanto point is the visual anchor of the design: a sharply angular tip with two distinct edge planes that emphasizes piercing capability and a strong, well-supported point.
Under the scales, the knife runs on caged ceramic ball bearing washers, a feature that is still uncommon at this price point and that promises a smooth, fast opening action with minimal break-in. The liner lock secures the blade, and the knife is set up for ambidextrous use, with a stainless steel tip-up clip that can be mounted on either side. At 4.61 ounces, the Ceyx is not a featherweight; the 0.12-inch blade stock and full stainless liners account for the heft, but they also give the small folder a planted, substantial feel in hand.

D2 at This Price: What to Expect
D2 remains the workhorse of the budget knife world. As a high-carbon, semi-stainless tool steel, it offers notably better wear resistance than entry steels like 8Cr13MoV or 14C28N, which translates into longer intervals between touch-ups. Heat treated to 59-61 HRC here, it takes a keen edge and holds it well through cardboard, rope and daily utility cutting. The trade-off is corrosion resistance that sits below true stainless steels, so owners in humid climates should wipe the blade down after use; the darkwashed coating provides an extra layer of protection on the blade faces.
The black G10 handle is a sensible partner for the steel choice. G10 is effectively immune to moisture, oils and temperature swings, offers a secure grip when wet, and adds no meaningful weight beyond what the liner structure requires. The 0.51-inch handle thickness gives the Ceyx enough girth for a full four-finger grip despite its compact 4.13-inch handle length.
Where It Sits in the Market
At $50, the KU335D competes with D2 and D2-adjacent folders from Sencut, QSP's entry models and CIVIVI's budget lines. What separates it is the combination of a tanto profile and caged ceramic bearing washers — most fifty-dollar competitors still run plain phosphor bronze or simple washers, and tantos are a minority profile in this bracket. Buyers who prefer a traditional drop point will have other options, but for those who want the angular tanto silhouette in a blackout finish, the Ceyx has little direct competition at this price.
The Verdict
The Kubey Ceyx KU335D does not reinvent anything, and it does not need to. It delivers a proven steel, a robust liner lock, a premium-feeling bearing pivot and a coherent stealth aesthetic for the price of a casual dinner out. The Ceyx KU335D is listed now at kubeyknife.com for $50.
