Re: The dirtiest four-letter word...
Damn, you made me look - I still have a set of Pyro pot crimpers and one of those nifty BICC ringing tools.
In the right hands, it was an art of electrical installation, I remember seeing a fairly nondescript church hall brought to life by the polished (not the bright orange or red covered stuff!) runs of perfectly formed Pyro - it really is a lost skill.
