Realised Ultimate Reality Pitons (RURPS)
Even smaller piton than the Reality Piton, some comment
"come on be serious now".
From the Black Diamond website:
The Realized Ultimate Reality Piton has
become standard equipment for nailing
minute cracks on major aid climbs
throughout the world. Developed in
1960, the RURP's ability to hold
infinitely small cracks has opened up
otherwise unclimbable routes. Weighs in
at 14 g (0.5 oz).
