Nuts: Eiger

Mike Sturm created Eiger Mountain Sports Corp. in the early 1960s. He sourced pitons from Switzerland, and had Stanley Brozek of S.B.C.I. produce carabiners for him. Eiger closed in the early 1970s. After closing Eiger, Mike Sturm built a similar company, Liberty Mountain, and sold climbing gear under that name. Around 1992, Liberty Mountain created the brand Advanced Base Camp for its climbing gear. Advanced Base Camp was reborn as Cypher in 2003.

Wired Hexagons

These are similar to some of my SMC Wired Tru-Hexes.
I do not like the large lower loop. It makes racking these nuts more difficult.

Irregular Hexagons

I don't know the official name for these. They are similar to the first Chouinard Hexcentrics. Like those and unlike later Chouinard Hexcentrics, these are symmetric front-to-rear.
