This cutler advertised in the directory (1856) as a pen and pocket knife manufacturer at Wadsley.  Ibbotson was a common name, but the individual may have been George Ibbotson (1829-?), who had been born in Ecclesfield.  He was the son of Henry Ibbotson (variously described as an anvil maker and spring-knife cutler) and his wife, Rachel.  George was grinding, aged twelve; a decade later he was a coach spring maker; and by 1861, a spring knife cutler in Wadsley.   He may have been the George Ibbotson, who after the Sheffield Flood (1864) claimed £25 for a severe cold and inflammation of the lungs (a claim later withdrawn).  Ibbotson’s later life is obscure, but he was widowed and living at Bradfield in 1871, when he was a striker.   In 1881, he was a blacksmith and anvil maker at Wadsley (and a cutler and farmer a decade later).  His death date has not been traced.
