If you order now, this item is expected to ship in two weeks.

This is the one and only Ultimate Hacking Keyboard, or to be more precise, the UHK 60, our flagship product.

The UHK is a fully programmable, impeccably built, open source, split mechanical keyboard – designed for extreme productivity and ergonomics.

Key switch type

Key switch type is the defining factor determining the feel of any keyboard. We offer six switch types, each with their own character and corresponding color.

If you’re just not sure which to choose, don’t worry! We suggest simply choosing in a left-to-right fashion – so if the Blue/tactile switches sound good to you, that’s the most popular choice. If Blue doesn’t sound like a good fit, Brown would likely be your next best option. And if not Brown, then choose Red. The first three options are preferred by most.

  • Blue switches are a great choice for hardcore touch typists since these switches have a highly tactile nature, but they’re the loudest of all so your environment must tolerate some noise.
  • Brown switches are also a good choice for typists because they’re tactile as well, though a lot less noisy than Blue switches. Given their internal construction these switches are easier to double-tap, making them preferred by gamers.
  • Red switches are primarily meant for gamers. They’re non-tactile, smooth to press, and super-easy to double-tap.
  • Black switches are similar to Red switches but stiffer, making them less prone to accidental key presses.
  • Clear switches are similar to Brown switches but stiffer.
  • Green switches are similar to Blue switches but stiffer.

As you can see in the product options, Brown, Blue, Red, and Black switches are from Kailh. Clear and Green switches are from Cherry, only because they don't have Kailh counterparts. We found that Kailh switches are just as high quality as Cherry switches, and it's easier to do business with Kailh for smaller manufacturers like us. So far, we haven't received complains about Kailh switches, and our customers love them. We don't plan to offer Cherry switches instead of Kailh in the future.

If you're still not sure which switch to choose, we strongly recommend purchasing a switch tester.


We only provide bar-shaped Enter key. The main reason is that it's more ergonomical than the L-shaped Enter key, and it's super easy to get used to, even for ISO users.


We only offer black keycaps with the printing options shown on the top preview image which are blank and US English with OS-specific key variations.

Please note that depending on environmental conditions and your skin type, keycap labels may become dimmer over time which is due to laser-etching, the technology we use to put labels on the keycaps. If you want to make sure to avoid label dimming in the long term, then blank keycaps are your best bet. Alternatively, see the layout and keycaps page regarding third-party keycap sets.
