Søren Refbjerg Rasmussen founded a company in 1969, which employed an average of 8 - 12 craftsmen in the 1970's. The semi-freehands they produced were traded under his prename Søren. Rasmussen himself finished only the very best pipes. So his way of pipemaking closely resembled the ways of Preben Holm, Karl Erik Ottendahl or Erik Nørding. Altogether more than 1,000,000 pipes were sold.
Today he works alone as Refbjerg and manufactures only a small number of pipes in his workshop in DK-2860 Søborg, which are considered to be tremendously precisely executed. The dimensions mostly range from small to medium sized, corresponding to his personal preferences. The shapes adhere to the classical models, but often he gives them a touch of Danish flair. Refbjerg accepts minor faults but never uses any fillings. "Straight Grain" is the only grading, used for his very best pieces. He likes stem decorations made of exotic woods or metal rings.
