i use two Petzl O crabs for my Hitchclimber system. I noticed the hinge side of the gate has some edges that are not razor sharp but theres enough edge to cut rope. So when i rotate the bottom crab to hook to my saddle, the eyes of my hitch are scary close to those sharp edges! I retired a hand spliced Beeline hitch because the strands looked to be damaged. So far, a stitched eye seems to not be affected......yet. I have been considering switching out to DMM.
