Structure in Balance

The rear view of Katina TKL is composed of three thoughtfully integrated elements: the lower case, an oversized external base weight, and a finely contoured weight plate. The generous use of materials such as stainless steel or red copper creates a striking visual presence, while the extended 18cm span of the weight block is balanced by elegantly curved crescents along its upper and lower edges. These flowing lines not only soften the sense of mass but also echo the hourglass-inspired silhouette of the keyboard’s side profile.

The Art of Light

Depth and order define the lower case, where a recessed arc engages in subtle dialogue with the base weight. Within this reserved space, two fading lines extend outward, reinforcing a sense of visual rhythm. A discreetly laser-engraved KATINA logo and a softly diffused LED—guided along the curved surface of the base—add refined detail and ambient sophistication. Through careful proportioning, intelligent layering, and precision mounting, the back achieves a harmonious and deep composition, free of visual clutter

Sculpted Silhouette

The side profile of Katina TKL is defined by an original "Dual-Arc Curve," inspired by the elegant contour of an hourglass. This flowing line is accentuated by a subtle inflection point, lending rhythm and softness to the form. Throughout the design, auxiliary lines—such as the waistline and bottom case line—are carefully integrated not only as transitions but as stages for light and shadow, establishing a harmonious visual order.

Floating Sensation

Emotionally, Katina TKL continues iNN’s exploration of a "Floating Sensation." Through precise coordination between the bottom case and external weight, a gem-like cut-out is subtly embedded in the middle. Visible only from certain angles, this restrained detail conveys a sense of quiet presence—as though the keyboard rests lightly upon the desk, inviting a moment of contemplation.

PCB Gasket Mount:

The internal assembly is suspended above the bottom case by the silicone columns, while limiting pins from the top case insert into the columns, restricting planar movement.

In this mode, the entire internal assembly makes no hard contact with the case. Simultaneously, the limiting pins introduce a subtle sense of firmness, giving a character best described as resilient.

With plateless mode and 3.7mm available travel space, the typing experience on the alphanumeric zone becomes notably soft and bouncy.

O-ring Mount:

Katina TKL adopted a configuration of 5 upper and 3 lower O-ring bosses to support the internal assembly.

It also employs standard D3.5 silicone O-ring and includes compatible clearance cuts in the plate for screw-in stabilizers. This delivers a typing experience that is moderately soft and acoustically focused.

The design is compatible with most mod parts and accessories readily available on the market,

e.g. Nexuros X Geon ‘s PCB Snap & Key Snap

Isolated TOP Mount:

The Katina TKL can also be configured in a top-mounted mode using M2 cup head screws fitted with custom silicone sleeves.

The degree of screw tightness can be adjusted to influence the down travel to some extent, while the plate makes only minimal contact with the screw heads.

This design effectively isolates vibration and unwanted noise, resulting in a solid typing feedback.
