I have inherited a great number of tools from my late father who was interested in all aspects of D.I.Y., whereas I have limited knowledge. Therefore I am having trouble identifying some tools. He accumulated tools from the 1950s onward and kept everything !The issue I have is that he sometimes bought good quality and other times “cheap and cheerful”. I can generally identify most as I go along, but I am struggling with some. In this instance I am trying to identify the background to some chisels. I am assuming they fall into the “cheap and cheerful” category, but I cannot find anything online. Can anyone help ? Please see attached photo
