Original Vintage CMI Crack Tacks

CMI Crack Tacks were postage stamp size pitons available from the mid to late 1960s through the late 1970s. Their basic design was similar to the bigger knife blade style pins from Chouinard but, due to their smaller size, the perpendicular eye could limit placement in some situations. Crack Tacks really worked best in horizontal placements where the perpendicular arm could provide a bit of  support and prevent the piece from levering out. These pitons were usually slung with half inch tie-off webbing or thin cord. Placements were almost always for direct aid and were “body weight” only.

The words "CMI 22'' are staped on the shell surface.
