Dane Lipscombe aka dlip/fata1err0r81 came up with this split keyboard sporting 5-way switches instead of the usual keys. The Harite is open source.
I considered the svalboard, but I wanted something more simple, cheap, light and compact that I could travel with easily – Dane.
The switches look very heavy on paper (1.2N lateral and 2.35N down, manufacturing variance is +/- 0.69N), but once you attach the sticks the torque makes them feel very light. It doesn't fix the issue on center though which is pretty stiff and not really usable in the author's opinion, especially for the ring and pinky fingers. Dane hopes that if this style of keyboard becomes more popular, we will get better switch options in the market.
By the way, the name comes from the sumo slap attack in Japanese ((張り手 or open hand strike).
