While working as an apprentice he began hand carving pipes as a hobby. Many were given as gifts to his more senior colleagues. Upon completion of his apprenticeship he moved to Nairobi, Kenya to work as a lithographer during the 1962 war. While in that war torn country, he was unable to procure pipes for himself. In the face of such a predicament, he chose to continue to make pipes for his own use rather than go without.
Returning to Denmark after three years he couldn't find a well paid occupation in his job, and so he began making a few pipes on the side to boost his income choosing his prenames "Karl Erik" - logo "KE" - for his label. When he managed to find some major Copenhagen pipe stores willing to sell his pieces his reputation grew little by little and he was finally able to purchase more and better machinery and began working full time as a pipe maker. One of the brands produced by Karl Erik Ottendahl was Champ of Denmark.
