The Freestyle2 keyboard by US manufacturer Kinesis has a zero degree slope that minimizes the height and creates a negative slope, resulting in reduced wrist extension.
The two modules of the keyboard are connected by a flexible pivot tether which allows an infinite range of splay. You can disconnect the pivot tether to completely separate the modules and keep them at any desired position within the 9 or 20 inches reach of the connecting cable. Find the perfect place for them to rest your hands on – in the most natural posture, equalling your shoulder width, no matter the body type. This reduces ulnar deviation considerably.
