Edelweiss Sheath Defect - Curve Unicore 9.8
|
Small or small diameter biners on those new or new-ish draws? Made by? |
|
The first two quickdraws i used on the first two ropes both had Black Diamond Positron carabiners on them. The third and brand new draw was a Cypher Ceres and the fourth draw was a Petzl Spirit Express. All of the draws were in fine condition, none of the carabiners were grooved or sharp. |

I've got one of these ropes as well, mine is a 70M bi-pattern. Bought mine in May and have been using it fairly regular (weekend warrior). It's got a handfull of short falls on it and one 15 footer when a hold broke on me last month. Have not noticed any major sheath issues like in Jay's photos. |

I experienced a very similar situation with and Edelweiss rope that was a friend of mine's and in some ways it was worse as we did not take any lead falls. The rope was brand spanking new when we took it out, climbed two steep routes and discovered no fewer than three big core shots in the rope when rolling it up for the day. I was flabbergasted to see that kind of damage to a rope that ran through a handful of carabiners and top anchors. I later went back and checked the top anchors to inspect for burrs and found none. There could be no other explanation for what happened that day than a manufacturing defect. |

I purchased a Edelweiss Flashlight II 60m 10mm Rope earlier this year. I had climbed on the rope between 6-8 times outside in Clear Creek Canyon in Golden, CO. All climbs had been sport climbs, single pitch, and in the 5.10-5.12 range. I was climbing at wall known as the New Hipster Wall and I was working on a 5.12a called Hipster. The route is very overhanging and is about 6 clips long. It is well bolted and I was using newer quick draws. I had flaked the rope prior to climbing and was switching ends after each climb. After 2 tries on the 12a I was lowering off the top when my belay partner noticed a core shot in the rope that was 10m from the end of the rope and it clearly needed to be replaced. After climbing on the rope for probably a total of 10-12 times and only over a few days, this is an issue I think should be addressed. Whether it be a warranty or manufacturing defect, is very concerning for a rope that has been barely used. |

That's what I saw as well with my "bad sheath" rope. Those pics (Red Rope) look like "Standard" damage over an edge etc. |

I had an experience where I was climbing with a few people who had brand new Edelweiss ropes. After just a few top rope climbs, the rope had some nasty sheath abrasion. However, I also have a friend who bought an Edelweiss 70 meter dual pattern (not sure exact model), and he loves it. Perhaps this defect is model specific. |

I have the Curve 9.8, not the unicore. It's seen two seasons of moderate use on a variety of rock. I chose it because it had good specs for dynamic elongation and because I found a good deal, though there was already questions about sheath durability. At this point I would not buy another. |
|
Petzl, Edelweiss, and at one other whose name escapes me have had this disintegrating sheath issue. Makes me want to boycott a whole company but I'm not sure that is the issue. I have a theory. |
|
I have the same rope as OP, Edelweiss 9.8 Unicore. I haven't noticed unusual sheath wear anywhere, although I haven't taken too many big falls on it, I have jugged on it a bit, and it seems fine so far. This is definitely worrying though. |

John Wilder wrote: Maxim figured out it was the red nylon in their lines that was causing their ropes to fail at 4 falls instead of 5- nobody would ever confirm it for me, but a little thinking it over tells me that its likely that there was a bad batch that got out of the source factory.The ropes they recalled was the Maxim Pinnacle and Apogee. The Apogee was red, but the Pinnacle was entirely blue. Here is a photo of it straight from the recall: In fact, they added red to the post-recall version. The pre-recall version has no red in the rope, and the post-recall version has a red tracer running through it to indicate it is post-recall. They also opened the line up adding a second color, which is mostly red with some black. Here is a photo: So how was the red the reason for the recall when the Pinnacle did not contain any red? |

Edelweiss definitely lost my business. This Flashlight II was brand new and was destroyed after after a few TR's on an overhanging sport route. My 2 partners and I probably have close to 100 years of climbing experience and checked for sharp edges on the rock, our draws, the chain anchors, our belay devices and there were none. Edelweiss quickly dismissed it as user error. I've destroyed ropes jugging, dropping rocks on them, working with sharp limestone and absolutely realized it was my fault and responsibility. But, for this brand new sheath to accumulate 30 feet of fuzz and completely rupture in 3 separate areas on the rope, Edelweiss must have envisioned one hell of a whipper..... |

Well, it seems there is definitely some type of higher-level supply defect with the red colored nylon. That's now six models from three or four manufacturers that are having problems, all different with the exception that they are red. I am surprised the manufacturers haven't been able to identify this yet when it's been well identified on M Proj. Or it is possible the manufacturers are aware of it, but are betting it will cost less to loose your business than do a full recall. |

That's now six models from three or four manufacturers that are having problems, all different with the exception that they are red.In the case of the OP's damage, and with mine, it's not just the red nylon. The op's was mostly the green. Mine is both. The frays on my rope look like there was several sheath threads spliced together at the same place at a couple of spots on the rope. The frays are not the result of an edge or snag. It is a manufacturing defect- or maybe more accurately just a poor method of manufacturing in doing so many thread splices at exactly the same spot. There are neatly trimmed edges just sticking right out of the weave, all in a cluster. With the OP's ropes, I dunno. Maybe it's the result of their dabbling in the unicore thing. Like the unicore bonded sheath can't handle the dynamic elongation of the rope so it bursts or tears to absorb the energy that the core should be bearing alone. Just a guess- I'm not a rope manufacturer. Would be worthwhile to determine the fall factor? In other words, was the rope elongating significantly while simultaneously being edged over the biner and causing heat/mechanical stress to the sheath? The op said that at first it felt like the sheath was hardening. I recall that the single-strand woven edelweiss ropes warn against fast rappels due to heat damage on the sheath that can cause core shots. |

So after blowing through those edelweiss ropes in 20 minutes I obviously didn't want another one, so I replaced the curve unicore with a Beal Booster 9.8. Unfortunately after only two months of occasional use this rope has also already been shot on one end. It basically just wore out really, really fast, it didn't experience failure like the edelweiss ropes did it just didn't hold up for any normal length of time. I attatched a picture that shows the end of the rope completely flat, soft and not willing to hold a coil anymore. Since Beal and Edelweiss are basically the same company i'm wondering if Beal has issues with their sheath's as well. It seems as if both companies are having major problems with quality control coming out of their factories. |

Actually it's both, as the sheath wore out extremely fast and then the core went to shit shortly after. |
