Wouldn't let a rope or slings near this thing.
I just ordered 2 which arrived today and I wish I had read the first review before I did. The edges really are sharp, which is not only inexcusable but unbelievable. The previous reviewer wasn't kidding when he said you can cut yourself with this biner. It probably wouldn't happen through casual handling, but you wouldn't have to work too hard to make it happen. And who knows what it might do to nylon? I'm not going to take that chance; I plan on returning them as soon as I can. Why a company as reputable as CAMP would produce such a thing is beyond me. I'm not sure if they were designed that way, or if someone at their factory in China fell asleep at the deburring machine.
