Figure Eights

Many figure eights are pretty much alike, if you rule out the Rocksport and steel ones as too heavy and the CMI Ultra 8 as too small. Most of the shape variations really don't mean very much. My own Open Eight is an exception. I used to use hard coated forged eights. They lasted quite a while, then suddenly the coating would wear through and the eight wouldn't last much longer. I switched to milled plate eights because I felt that there was less chance of manufacturing defects, but I think this wasn't really a valid concern. I rarely use eights any more (now that I have some superb titanium mini-racks in the same weight range: too bad that these are available no longer), but if I did, the DMM Cardiac Arrester would be my choice - because it is so pretty and has such a neat name. Of course, it works as well as any eight.

As I said, all of the midrange eights are pretty much equivalent, but look at the extremes. Compare the size and weight of the CMI Ultra 8 with the Rocksport! For general use, I don't see any reason to choose an eight that weighs much more than 150 to 200 grams.

According to Pit Schubert (Bergunsteigen 3/06), the figure eight was invented by Dr. Max Pfrimmer, a physician who worked with the mountain troopers medical corps in St. Johann, Tirol, Austria, during WWII. Pfrimmer documented his idea for a lowering device in his diary on October 1, 1943. Only in the latter 1950s did Pfrimmer consider using his eight for rappelling. Pfrimmer offered his idea to Schuster's sports equipment store in Munich, which commercialized their eight in the early 1960s, but without success. Another early figure eight that I own is the Fisher, Version A, which appeared in an advertisement in the June 1963 issue of Mountain Craft. (The Famau is earlier, with the patent applied for in January 1941. I view the Famau as a Figure Eight with Ears, which would give its inventor Jean Briod priority).

The earliest figure eight appearing in the USA that I know of was one was sold for $3.50 in an Adirondack climbing shop in the Summer of 1965 (Bill Craig, Nittany Grotto News, XIV,1, pp.4-5). That eight was made in West Germany, welded from 1/4" [6 mm.] steel rod, was 140 mm. long, and had hole and eye internal diameters of 47 and 35 mm., respectively. This was probably Schuster's eight. Various people used eights after that, but it wasn't until after CMI introduced their hard-coated eight, which I first saw advertised in the October 1974 issue of Off Belay magazine, that the popularity of the eight took off in the USA. The CMI Standard is still in production.
