Black Diamond athlete Sonnie Trotter rolled through Salt Lake City this past spring on his way to Indian Creek and stopped by BD HQ for a quick hello. He said he wanted make his own carabiner, so we took him downstairs to the carabiner manufacturing area real quick and ran him through most of the process: bending the rod stock, forging the biner, trimming the excess, heat treating it, running it through tumble and polish, installing the gate, and pull testing the finished biner.
