Everyone seems to use the plastic clippers from BD and Petzl. I do as well but I don't know many who haven't broken one or lost screws at one point or another.
I think there is a market for a hot forged aluminum....racking specific biner......... in the $20+ retail range. I mean come on!! Loose one screw and it is $60 these days!!! $20 would be a bargin for a hot forged clipper done right. I'd prefer the Petzl pattern myself and no rubber bands or tape. BD? Calling BD??!!
Come on guys..."do it for the children" :-)
But till them Joe has a good idea. Good enough I am going to go looking for some big biners this week.
