In 1971, Yvon Chouinard threw on to the market the Regular Hexentric invented by himself and Tom Frost. A much improved Hexagon, it was however still symmetrical and did not allow more than three different settings. The real revolution landed in 1974 with the Polycentric Hexentric which, this time, allowed four settings. A Norwegian, Tomas Carlström, had given the idea to the Chouinard / Frost team some time before. Trying to make copies of Chouinard symmetrical Hexentrics himself, Tomas Carlström took two old Clog Hexagons and machined them. But since his tools were not very precise,he was first disappointed by the asymmetrical chocks he had made. Then, eureka(!), he discovered that they worked in one more position than the original Chouinard Hexentrics. In 1972, Chouinard increased his hardware line with a set of seven Stoppers which were to be the subject of many improvements during the following years and become in the USA, the reference for the pyramidal nut. In 1973 and 1975, he produced the Tube Chocks which covered the four to six inch offwidth cracks and the Crack'n-Ups that protected the ultra-thin vertical cracks. With Chouinard Equipment, the Americans had all the necessary tools for their new ethic, all nuts or hammerless.
In the USA, other manufacturers made their way into this new market. Bill Forrest was building in 1969, what was later to become the ultimate aid climbing weapon, which actually was at that time a nut, the Copperhead. A small copper cylinder was swaged around a single wire. Bill Forrest kept the system of the simple wire for two of his other creations: the Foxhead in 1970, a pyramidal nut in aluminium alloy or in plastic, and the Arrowhead in 1974, a very slim copper nut. The Forrest nuts also existed in an S version (short wire), being more convenient as aid climbing devices.
In 1973, Kris Walker and Bill Forrest developed the Titon, a T-shaped nut, in steel for the small sizes and in color anodized aluminium alloy for the big sizes. In response to the article The Whole Natural Art of Protection from Chouinard, in 1974 Forrest Mountaineering proclaimed all the assets of the Titons in Chock Talk in its Catalog and Guide to Natural Climbing. This prolific manufacturer would also go on to develop a line of P-Nuts (1982), a slice of steel mounted on a length of wire cable, and the Triton (1985), which may be used as a nut, a belay plate and a rappel device. His Roll-Your-Own (1984) will remind US climbers that, somewhere in Germany (Elbsandstein), people also climb very clean. At C.M.I. (Colorado Mountain Industries), the Hexachoks resurrected the Hexagons' design but these were lightened to a maximum degree and had a 1/8'' web in the centre producing an effective " I " Beam. With this manufacturer, we found again in 1975, the H-shaped streamlined aluminium alloy extrusion, to produce a set of twelve Beamchoks very nicely finished in blue, of which the biggest was eight inches long.
" ... like a tight-rope walker, the climber is moving feverishly five meters above his very last protection, an RP number 3... ". He who reads such lines immediately feels his palms becoming sweaty. The man behind these two initials is Roland Pauligk. Living in Mordialloc, a small town in the South suburbs of Melbourne, he emigrated from East Germany in 1960, one year before the construction of the Berlin wall. Since the mid seventies, in a small workshop in the back of his garden, the boiler maker Roland Pauligk makes with an extreme meticulousness the ultimate tools for hair line cracks. Troll and Chouinard already produced small nuts but a silver soldering process allowed the RP's to be far narrower and even thinner, whilst maintaining maximum wire strength. He mainly sold his micro brass wedges in camp sites during his climbing trips around the world (Yosemite, Cloggy, Chamonix, Dolomites). The breakthrough came when Rick White, who was a top climber, did " Gumtree " at Mt Buffalo hammerless in 1975. The smallest RP was a size 1. After the ascent he said to Roland you need a smaller one size 0, as the 1s were only half in a couple of critical placements. There were virtually no peg scars on " Gumtree "; it had only two previous ascents both in December 1972, the first and Rick's repeat a week or so later. The critical placements were between crystals. There was no write-up by him, probably just climbing news reports by others. Rick said RP's were part of every Australian climbers rack in the early to mid seventies and beyond, which significantly boosted the orders. He showed them to Yvon Chouinard in 1977, which led to his range of micro-nuts! Roland Pauligk is the representative of an Australian quiet way of living and he has never wanted his business to grow too much, so the manufacturing of his superb toys goes on when... the weather is not quite settled.
In the USA, in 1979, after extensive research Gaylord Campbell marketed two series of nuts superbly crafted and color anodized the Wedgefasts and the Saddlewedges. A notch on each one of the two big sides guaranteed the Saddlewedges a better stability. In 1986, D.M.M. (Wales) would bring back this idea for the famous Wallnuts but, ten years before, in England, Tom Proctor had already thought to scoop the widest faces of his larger Clog Wedges. Awesome work was done by Gaylord Campbell to increase the radius over which the sling passes and to improve the perfection of the path of the sling into the nut. The instruction booklet supplied with each Campbell Mountaineering nut was, by itself, a little wonder and a masterly course on chockcraft.
Of all the simple geometric shapes to choose from, only the cam was not selected for a nut at that time. This was without counting on Greg Lowe, called Inventor Extraordinaire by Glenn Randall in the magazine Rock & Ice in 1986. In 1972, Greg Lowe, assisted by his brother Mike, refined the concept of the cam by introducing the constant angle, as a fundamental element for the stability of future nut placements. In 1973, he created his first prototype Tri Cams but they only came on the market in 1981. The only solution in specific situations, the Tri Cams are the most fun to use, stimulating the climber's ingenuity. In 1976, C.M.I. brought onto the market the Kirk's Kamms, a single thick block of cam bound to a single wire by a swaged stainless steel ball. The ball itself at the end of the wire was also marketed as the Blue-Bells and could be used as a small nut. With the Camlock in 1977, S.M.C. (Seattle Manufacturing Corporation) built a hybrid device from a Hexentric and a Tri Cam, better adapted for non-flared cracks.
