This is a semi-hardened steel forged piton for thin, parallel-sided cracks in limestone or granite. 
 
The larger the area of contact of the blade of the piton in the rock after hammering it in, the better the piton will hold. In horizontal pitons, the eye of the piton is at right angles to the blade. These pitons are used in flush, horizontal cracks and in offset or open-book type vertical or horizontal cracks. They are recommended for use in vertical cracks instead of vertical pitons because the torque on the eye tends to wedge the piton into place. This provides more holding power than the vertical piton under the same circumstances.
