A fine little set of wired nuts donated by Gilbert McNeil which don’t look like they’ve been used an awful lot. We’ve never seen the older Chouinard Hexentrics on wire before and think they must be very early versions and also the little sliding metal sheath is something we’d not seen before either – presumably it was designed to help with the placement. Hexentrics were invented by Yvon Chouinard and Tom Frost with a little help from a Norwegian, Thomas Carlstrom and a patent was granted in America on April 6th 1976 – that patent has now been transferred to Black Diamond. The most likely scenario is that Clog Hexagonals were made before Hexentrics were invented. Interestingly, the clog wired nuts in this bunch are hexagonal, not hexcentric, i.e. not offset. Presumably Clog were not able to use the patented idea, though it’s not clear if there was a UK patent, as Clog were based in Wales.
