Don't take this lightly. One swinging fall could mean curtains. It's very easy to cut a rope under tension.
Edited to add the following quote from a guy who makes ropes at Sterling. This is in regards to the "sharp edge test" used to certify some ropes:
In reply to: After the edge standard was introduced I did a bunch of tests using an actual piece of broken granite as the edge. Even with a fall factor WAAAYYYY below 0.5 none of the certified ropes held. Later I resorted to simply lowering the 80kg onto the rope without dropping. Once the rope was fully loaded with the mass I allowed the rope to roll slightly across the edge. Again none of the ropes held. <snip> The broken piece of granite was pretty damned sharp but I could easily walk up to any granite cliff and find edges that are sharper.
GO
