Lightweight and strong.

The Black Diamond Lost Arrow Pitons are light enough that you may forget they're on your harness. But when you're in a thin-to-medium crack and need pin-worthy protection, these bad boys get the job done. Black Diamond crafted these out of hot forged steel to keep the weight down (#1 weighs two ounces) and the strength up. Each piton has a number so you can find the correct size during critical moments where you can't shuffle through all your gear.

  • Hot forged steel
  • Numbered

Aid Climber's Paradise!

  • Familiarity:I've put it through the wringer

Or are they a pair of dice?

Nail up - i had the (un)fortunate experience of hand placing one of these puppies in a forgotten route in the Wasatch range - although not ideal - it served to calm the nerve and keep me up on the sharp end.

The aid climbers workhorse. make excellent rappel pieces as well!
