Serene Industries 'The Cleaver': Single-Block Aluminum Hall-Effect Keyboard

Cut from one solid billet of 6061 aluminum, the same alloy specification used in aerospace hardware, The Cleaver represents Denis Agarkov's most refined argument yet for the monoblock keyboard as a category-defining object. The Serene Industries founder and filmmaker-turned-designer debuted the board last April, drawing on collaboration with the Paris-based studio Waiting for Ideas for its aesthetics and on his own engineering post-mortems from the Icebreaker, the company's $1,600–$1,700 debut.

The case for CNC-ing from a single block starts with what you eliminate: flex, resonance variation, panel gaps, and alignment tolerances that haunt multi-piece assemblies. The Cleaver's chassis, electronics, and silicone core are fused into one integrated unit, and that silicone overmold does triple duty as non-slip feet, electronics seal, and acoustic dampener, producing a sound signature that emerges from the material itself rather than from foam sheets stuffed between parts. The PCB is silicone-potted for dust and splash resistance, and the 1/4-20" threaded insert embedded into the body, carried over from the Icebreaker, opens the door for camera rig-style mounting setups that most keyboards cannot physically accommodate.

At 365 mm × 110 mm × 17.5 mm, the Cleaver is nearly 3.5 inches shorter than the Icebreaker and substantially slimmer, running just 17.5 mm thick where the predecessor measured 24 mm. Despite the low profile, Agarkov kept full-height switches beneath aluminum keycaps that are each laser-perforated with 1,204 micro-holes, up from 800 on the Icebreaker, allowing per-switch RGB backlighting to push through the metal in a way no PBT doubleshot can replicate.

Monoblock construction also defines what the Cleaver is not. There is no wireless connectivity. Agarkov dropped the Icebreaker's Bluetooth and 4,000 mAh battery to achieve the slimmer profile, leaving USB-C wired as the only option. What the chassis gains in rigidity it sacrifices in modularity: the integrated build is not designed for the kind of teardown-and-rebuild culture that drives most of the enthusiast market. The Hall-effect switches are hot-swappable, but the body itself is not a traditional tray-mount or gasket-mount puzzle you reassemble on a Saturday afternoon.

Three adjustable typing angles via magnetized feet, replacing the Icebreaker's fixed wedge, represent the most meaningful usability change and the reason reviewers flagged the Cleaver as "actually travel-friendly" for the first time in Serene's lineup. It ships in Clear (raw aluminum) and Black, in both Windows and Mac layouts, and is manufactured entirely in the United States, with production commencing two weeks after pre-orders close.

At $850 on pre-order, the Cleaver costs roughly half the Icebreaker's asking price, which repositions the brand meaningfully without abandoning the brutalist design DNA rooted in Agarkov's longstanding interest in the Flatiron Building and avant-garde Russian literature. For the buyer who wants a structurally unrepeatable object on their desk, one whose acoustic properties and typing precision derive from how it was machined rather than how it was assembled, the Cleaver makes a case that Serene Industries has been quietly building toward since the Icebreaker first proved the concept.
