Abalakov thread

The Abalakov thread is a common method of protecting oneself while ice climbing because it is easy to create, does not require the sacrifice of expensive gear, and can be very safe when used properly.

Because of its safety and convenience, the Abalakov thread is considered one of the most significant innovations in ice climbing.

The holes need to be drilled at the correct angle (about 45–50° compared to ice surface), and care must be taken that they interconnect.

[1] A 2009 finding and experiments have shown a vertical rather than horizontal arrangement of the holes to be stronger (12%) (Smith, 2009).

[5] Typically used in ice, it is sometimes also used in canyoning when traditional bolted anchors have been or will get damaged during the wet season.
