A long, long time ago, a tripod company called Vinten made a particular type of tripod, which at the time was unique, unusual and certainly unlike anything else on the market.
It was called the Fibertec. Released back in 2002, as this old article explains, it…
…gets its strength from unique “channel” sections of a carbon/glass composite that enables these legs to out-perform the traditional twin tube design.
That it certainly does. At the time of writing that article back in 2002, the Fibertec set of legs combined with a Vinten Vision 100 head cost around £9000. Being unique has its price.
