If you like rock climbing history these are just the thing, and a little bit special, being a couple of very early Clog brass hexagonals dating from around 1970. At that time the two UK companies, Troll and Clog, were vying for a share of the market – though apart from the different names stamped on each one, it was sometimes hard to tell one from the other. Denny Moorehouse, owner of Clog at the time, is credited as being the inventor of the hexagon shape.

Quite why the smaller ones were made from brass we’re not sure, but the idea did not last and very few were made, which makes these fellas a bit rare.

We think that founder of our Heritage Collection, Mick Tighe, was using these ones way back in the 1970s when he was a climbing instructor in the Royal Marines.
