    Negative blocking: can we find better words?

    dynamic vs. static (load) rigging would by my suggestion too. somehow it makes perfect sense, doesnt it? the only confusion might come up with the dynamic acton of the groundie on the lowering line, but thats not a big deal I'd say negative blocking doesnt make sense to me, whats positive...

    What are the best Scissors ?

    WOW, that sounds mighty impressive! It could really be worth the price if it stays sharp cutting all the high-mod stuff! I know of scissors more then double that price which do not...

    What are the best Scissors ?

    Cool, how do sharpen them? Are they "micro-toothed"? I know Marine-Splicers who work work with high-end-scissors as well, but they send them to the manufacturer for sharpening. Quite expensive all together...

    ISC D4

    I just watched the little instructional video on the ISC product page here: http://www.iscwales.com/Product/RP880-D4-Work-Rescue-Descender/?from=%2fBy-Industry%2fIndustrial%2f One thing is very interesting: The D4 is the first device I hear the manufacturer give its ok NOT always to use a brake...

    What are the best Scissors ?

    This thread is about cutting High-Mod fibers, right? I just want to get sure, and again want to make my recommendation NOT to use expensive scissors on them.

    ISC D4

    The D4 is nice, but my first thought holding it in my hands was "damn is that thing heavy"! I know some Tree Climbers will love that, but comparing it to a Petzl Rig it feels like being made of steel totally... No real world experience so far to be honest. I like that its possible to run the...

    Petzl Zillon for DdRT?

    No, but in the lower D rings. Its ok, my comment was about the use in "single-leg-modus". I still see no real advantage to the ZZ for climbing. Have you seen the ZZ yet? Bulkiness is not an issue of this device, more the opposite...

    What are the best Scissors ?

    I second the carpenters knife with exchangeable blades. There are super (-expensive) scissors for that, but they get dull with time (quite fast actually) as well and sharpening them is not easy.

    Petzl Zillon for DdRT?

    No way it'll be better for Ddrt than a Zigzag, so why do you think of that? It even will not be very much cheaper because you have to buy it with some rope in it... The Zillion has 1 "Zig" part less in the grabbing part of the device as the ZZ, so it releases more easily. Which makes sense on a...

    Name change

    I think exact terms for the different rope climbing techniques would be great! Unfortunately the ones mentioned so far dont attract to me at all... In the German language (my mother tongue, I am from Austria) its even worse!

    To Ring or Not to Ring?

    Yes, mainly the orientation of the biner thing and another advantage is the abrasion from the bridge gets spread around all the inside of the ring because it moves. On a biner you always abrade the same spot. I know its not a big issue (except on Aramid-cover rope- bridges)... I run the small...

    High-mod fibers and aging, UV-degradation etc.

    In the meantime I've heard from companys working with Technora and Kevlar, UV Degradation is not a big problem, or at least self abrasion is the much bigger one. But no still data for all this. UV is a problem vor Vectran and especially for PBO (which is the strongest, most static and most...

    aramid fiber and bridge failure

    As far as I've heard from companys working with Technora and Kevlar, UV Degradation is not a big problem, or at least self abrasion is the much bigger one. But no still data for all this. UV is a problem vor Vectran and especially for PBO (which is the strongest, most static and most expensive...

    Splicing a split tail?

    I remove a pair every 4 strands on 16-strand rope, so 8 strands are remaining on the taper. I thought thats the standard to be honest! Anyway, it works fine... :) Anybody else doesit that way?

    retrieving my Pulleysaver

    So, these should be the golden rules, right? :) A pulley saver like the Teufelberger can easily be homemade. When buying one I'd go for the ART Rope Guide, its merely more expensive and far more developed I think. Maybe the price difference is much bigger in the USA. I use none of them, just...

    lock stitching with Braided Nylon or Zing-It

    As I know Dyneema for stitching weakens the splice more than Polyester or Nylon, because its so "sharp". The difference is measurable, some splicers I know did their testings. I would not use Dyneema fishing line. Tuttle, did you do comparison on the stitching material with break tests as well...

    Splicing by Tuttle

    Cool, now we're talking, thanks. So Tuttle (like Robert DeNiro in Brazil btw., right?), can you compare strength tests of "usual" 21x rope diameter fid length splices to your 15x? Would be interesting. And do you use this measuring on all C1DB, I mean climbing lines, rigging lines /-slings etc...

    retrieving my Pulleysaver

    Interesting comments, I always wonder why so much Arbos buy a Pulley Saver nontheless?! Maybe someone can enlighten me... You guys know that the updated version will have a Pinto instead the bigger Pinto RIG? Should help on retrieval a bit I guess...

    Splicing with X-Rigging Rings

    Re: Re Tuttle, pleas start a new thread with some splicing specific topics where you can tell us something about your tricks. Like how you shorten/modify the measuring for a C1DB climbing line f.e.., or e2e's or whatever seems relevant. We then could talk about content and not form, which is...
