Gibb Tools are specialist tool supplier to the industrial and retail sectors, with offices in Aberdeen and Ghana. Their main but not exclusive business is the supply of engineering tools to the North Sea oil industry. Gibb Tools was established in 1933 and traded as a retail outlet until the 1970's when the oil industry arrived in Aberdeen. Since then the oil sector has become an increasingly important part of their business and they have changed their stock profile to reflect this. Large in-house stock combined with quality service has meant fast growth to the company.
