The is one several nearly identical odd-shaped,
bent figure eights. Here are several that I have collected:
The bend allows these eights to be rigged two ways with differing amounts
of friction. The rope hole is shorter than normal, so the high
friction position may provide too much friction on stiff or muddy
ropes. The short overall length and sharp bends makes this eight
rather "grabby" when using the high friction arrangement
on sandy ropes.
None of these eights have slots for sticht-type belaying, and their round eyes are not designed for that purpose.
