Kolstrand...a short history


In 1929 Amandus Kolstrand, a fisherman, saw the need for power equipment and fishing gear improvements. He designed and manufactured the power salmon trolling gurdy, shock absorber, trolling block, line snap and snubbers for the salmon trolling industry. Later he sold Kolstrand to Thomas Breiwick.The Kolstrand Building 1937


Thomas Breiwick was born on January 11, 1893 in Breivik, Stokmarknes, Norway to Elling Lorence Olsen, a fisherman and small farmer, and Thea Bergitta Sorensen, a homemaker. There were eleven children in Thomas's family, but the first four died shortly after birth. Thomas attended school for seven years and then fished with his father. Feeling that he was lacking in education and opportunities, Thomas decided to emigrate when he was seventeen years old in 1912. He had an aunt and uncle in Tacoma who lent him the money for a ticket. After arriving in Washington, Thomas got a job at a sawmill in Selleck and later did road construction in Tacoma. Thomas's uncle was a mechanic for Northern Pacific Railroad, but when he grew tired of working in the shop, he invited Thomas to start fishing with him. As it turns out, Thomas's uncle did not like it, but Thomas continued fishing for the next thirty-five years. He eventually owned nine boats.


In 1942 Thomas Breiwick and his son, Arnold Breiwick, themselves high-line fishermen, purchased Kolstrand from his friend, Amandus and formed the foundation for what is now one of the foremost companies to manufacture and distribute commerical fishing equipment and hardware.


Today Kolstrand is recognized world wide for its expertise in salmon and tuna gurdies, halibut gurdies, seine winches, anchor winches, gillnet reels and rollers long line reels and haulers, power blocks, and other products as well as customized needs. The key to Kolstrand's Success is the quality and dependability.
