    Is the problem reduced by using a knot block instead of a biner block?

    Reduced, yes. Eliminated, no, and other problems are introduced. Small ropes + big rings = the knot getting stuck in the ring.

    Thanks Tom.
    I'm an engineer - which includes some machining at times for fun.

    Rapterman - It's UHMW PE.

    And to Yellow Dart, glad your favorite color isn't blue. ;)
    I don't know how to sell stuff... but I suppose I could get something figured out.

    The post above is me... I certainly confused myself. It seems I accidentally created a new account or something when I installed Taptalk.

    Have a seat and click my link:

    So, this isn't as sexy as my Cog, but I thought it kind to share something I learned from my EDK :) It works best with a rapide, but a rap-ring will do also. AND, for those who love gear - don't forget about The Cog.

    Yeah, but... it is still the rope running across the surface. Better than standard biner block, but, I think the COG would be better still.

    That really wasn't the point of the post. But, did you know Dyneema is UHMW-PE?

    I had this happen to me years ago on the second rappel in strike 2 canyon capital reef with a brand new bright orange blue water 9 or 9.2 canyon rope and was shocked that the core shot was on the block and had never heard of that happening when I asked around and still have not heard or read of it till now interesting just thought it was a fluke. Makes sense I've usually set the ring near or over the edge anyway. Good to hear it is a thing that can happen and nice to know to be aware of it. Another thing to note is I had a blue water Canyonator short rope that I marked the middle with a simple X used a sharpi permanent marker and got a miner core shot in a canyon on the final rap right where the X in the middle of rope was. this was years after I marked it and the core shot was miner but was caused due to the ink I believe. if your gonna mark the middle of a rope make sure your using middle mark rope safe dye.

    Would the quicklink trick also be useful when tying two ropes together with overhand knots?
