This is yet another fun key, although like all my latest fun keys they have a serious very useable action, it is a responsive finger tip type, with a very low slung handle, I've constructed it mainly of 25mm brass bar disks which at the moment I have a good stock of, although it looks a bit strange and unusual it does incorporate certain dimensions and tensions that have given it a very nice action, the bearings used are ex Hard drive so are of exceptional quality, I have embedded them into the holders with a synthetic cement just as they were fitted in the hard drive, this method provides excellent alignment, Sometimes a key starts to take over like this one, and becomes a bit of a monster, now much taller and heavier than I anticipated and has been far more difficult to make than I first anticipated however it is quite unique, I have changed the original knob to a far heavier type giving it a better balance, and the key is now very pleasant to use and easy to adjust with its Neo disk magnets, I like it :()
