In 1970, Sid Tool purchased the cutting tool marketer, Manhattan Supply Company and changed the name of the company to MSC Industrial Direct, using the initials of Manhattan Supply. In 1978, MSC became one of the first distributors to launch a fully integrated Quality Assurance Department. In 1976, his son Mitchell, a lawyer, joined the company and was tasked with seeking out the best practices at other industrial suppliers to implement at MSC. In 1982, Mitchell replaced his father as president of the company. The company went public in 1995. MSC went on to become one of the largest industrial equipment distributors in the world with $1.87 billion in sales in 2010.

After serving in the Army Air Force during World War II leaving the business first, in the hands of his brother (until he too was drafted) and then his sister while he was gone. He returned to a company with $36,000 in annual sales where he soon landed exclusive contracts with Grumman Corporation and Republic Aircraft. In 1955, he moved the company to Plainview, New York, closer to his home in Great Neck, New York. Sensing that he was overly reliant on the two aerospace companies (they were 90% of sales in the 1960s), he launched a catalog business to diversify his customer base. His colorful catalog (known as "The Big Book") combined with an expansive portfolio of lower cost imported tools purchased at a discount (Sid Tools was the first company in the industry to widely import foreign-manufactured tools) propelled catalog sales which soon exceeded the company's regular sales. After an inventory problem where he ran out of stock of a critical item, Jacobson invested heavily in computerized inventory management and order processing, the first to do so in the industry.

Jacobson was born to a Jewish family in Brooklyn. At the age of 16, he took a job as a machinist and in 1941, he founded the Sid Tool Company in Little Italy, Manhattan with $1,000 of his own money and $3,000 borrowed from his mother. Sid Tool sold cutting tools to New York City machine shops.
