In reply to tehmarks:
Ok, so this is starting to make more sense. Bicoins are nuts, parabolts are bolts, clavos are pitons and gancho apparently translates as hook - presumably in the aid climbing sense of a skyhook or similar. Which just leaves the questions, what the hell is a buril, and what is the difference between a spit/espit, and a parabolt (one of the guidebooks seems to make a distinction)?
