I suppose we’d better point out that these ‘razor blades’ are for rock climbing, not shaving! The little label that came attached to them uses the term ‘micro pitons’ which might be a better description, ‘Clog’ is also on the label, though there is no Clog stamp on the pitons which is unusual. American mountaineer, Yvon Chouinard, created the first micro piton back in the 1960s and called it a ‘RURP’, Realised Ultimate Reality Piton, and we suspect that Denny Moorehouse, who owned Clog back then, decided to make his own version, which he did with lots of other pitons.
So, we’re calling these two little fellas ‘razor blades’ as that’s what they are listed as in the 1972 Ellis Brigham catalogue above (item A9). They look very similar to the ‘RURP’ described in the 1978 Chouinard catalogue above. Either way they could be called ‘micro pegs’ – take your pick!
