Franz Bachmann
edit_ _ There's a Franz Bachmann mentioned on the Web (2 hits at 3 sites by Googling
- "Klemheist" "franz bachmann"
), for developing a variation on the klemheist, "FB sling-friction knot". So is he the Bachmann of the Bachmann knot?
_ _ Hmm. 4 FB-knots, including that one, at Entwicklung der FB-Knoten ("Development [i think] of the FB-knots")

_ _The "FB sling-friction knot" is not a variation of the "Klemheist" but of the "Hedden knot"83.76.173.253 16:46, 25 April 2007 (UTC)user:Riehener,25.April 2007.
How is this knot used? Where's the load. How much load? Are we talking carrying a body or just a few extra carabiners?--Sparklingpoolcare 04:34, 4 September 2007 (UTC)
- Frequently used in crevasse rescue as a clutch in a pulley system. Thus it can be expected to hold the climber's weight minus friction. Tens of kilogram force, anyway. In fact, it's far stronger than that. 6 mm prusik cord is not known to cause damage to nylon ropes in this configuration, and the breaking strain is 13.9kN. The rated strength of the karabiner is irrelevant. Load is applied to free end of cord, and to rope. Both have massive individual strength. Transfer of load between the two occurs by friction. In short, you could probably dangle a ton off of it statically. If you wanted to release it, and let the rope slip, you'd want far less, though.--Che Gannarelli (talk) 14:54, 23 April 2009 (UTC)
