Black Diamond Lost Arrow Piton

Patterned after John Salathé's original designs and hot-forged from steel for repeatable placement cycles, the Lost Arrow Piton from Black Diamond is the standard choice for thin-to-medium crack aid placements and fixed protection on alpine routes. The series runs eight sizes (No. 1 through No. 8), spanning thicknesses from 4mm on the No. 1 to 9.5mm on the No. 4, with short and long variants across the range for varying crack depths. Per-unit weights run from 56g (No. 1) to 114g (Nos. 7 and 8), keeping the rack manageable on extended aid objectives. The forged construction is built to withstand repeated placement and clean without deforming through sustained use.
