We got these rather unusual ‘hexcentrics’ by doing a swap with a guy on ebay; he was selling them- we couldn’t afford them so we swapped them for some of our excess gear.
They are obviously hand/home made and based, loosely, on the design of a Chouinard Hexagonal though with a rather square style which probably relates to whatever piece of aluminium they were created from.
Unfortunately, we don’t know who made them, but they are well made and have been well used so we are delighted to be giving them a little bit of life in the hereafter.
