I'm stuck trying to come up with an appropriate size handle for this elevation wedge (quoin). The wedge is tiny at 2mm x 3mm & I wanted to use a belaying pin for the handle but the one shown is 10mm long-way to big. I see belaying pins for sale as small as 6mm. Does anyone know if a 6mm pin would be small enough for this wedge? Any other ideas on what I could use for the handle or should I just skip it?
