Some history:
Source: B.C. Provincial Museum
By 1941 the well-known saw manufacturer Spear & Jackson (B.C.) Ltd. was also manufacturing a chain saw but apparently there were early design problems; one customer was lost when Wellburn Timbers Ltd. informed the firm that they were returning the saw as it had broken down "so often that we have no confidence in it ".

From Wikipedia:
In 1760, Alexander Spear and John Love formed a company in Sheffield called Spear & Love. In 1814, John Spear, the nephew of Alexander, took on an apprentice called Sam Jackson. In 1830, the partnership Spear & Jackson was formed.In 1889, James Neill patented composite steel - steel-backed iron. He registered his composite steel products under the Eclipse trademark in 1909. The name was taken from the famous racehorse Eclipse, who even though he had died over a hundred years earlier was still famous for his dominating success. The phrase "Eclipse first and the rest nowhere" was still in such common use that Neill adopted it as a marketing slogan for his products. Eclipse made the world's first composite steel hacksaw blade in 1911. The company began manufacturing hacksaws in 1924. All hacksaws are now built according to their design.The Spear & Jackson brand is owned by Hong Kong-based United Pacific Industries Limited having been bought initially by Neill Tools in 1985, when known as Spear & Jackson International plc. James Neill Tools, previously a family-owned business, initially made a public issue of shares in 1970. In 1989, the business' centenary year, Neill Tools was acquired by the MMG Patricof Group, which said it wanted to expand the business and refloat in c.5 years. In 1995, Neill Tools renamed itself Spear & Jackson plc. Its headquarters have always been in Sheffield.
