Hey friends. Sorry I am late to the party. I posted a similar blurb in the Fricton Hitches thread earlier tonight...
I do my best to learn and use the correct terminology and so instead of writing things down in my own personal notes, I am regularly updating the dictionary on my website. It's a work in progress, but so is everything, right? Below is what I have gathered on the tend / tender / self tending topic. Comments welcome. By the way, using cordage as a tender is not something I have seen before. It's typically a rigid device so as to minimize rope rubbing on rope in a concentrated area.
tend / tender/ self tending
Tend: An action/verb causing the movement of a friction device in a desired direction. In rope climbing ascent, the friction device is tended upward for progress capture, removing / minimizing slack in the system.
Tender (or Tending Device) is a device which tends a friction hitch in the desired direction. Pulleys, rings and carabiners are commonly employed as tenders.
Self Tending: The literal definition applies : Tends itself. In the context of describing a system vs a hitch, there are subtle differences.
Self Tending System: A self tending system is one which has automatic progress capture, requiring no manual action to advance the friction device. Example: “Double Blake’s Hitch MRS System”. Note that a self tending system might use a tender.
Self Tending Friction Hitch: One which allows the removal of slack with only one hand by pulling on the tag end of the rope and without the use of a tender. Example 1: Shorten a Tether or Lineman’s belt with one hand. Example 2: Climber is connected to the tree via a friction hitch to a Lifeline which is secured to the tree. Climber steps up, introducing slack, and pulls the tag end of the rope outward and upward, removing the slack with one hand.
