A collection of tools designed and devised by Leonard C. Evetts for use in his lettering and stained glass work. These include three rulers used to create lead lines for his window designs, double pencils spliced together with masking tape so that two lines can be drawn together and a double headed wooden tool which holds two pieces of chalk which he used for making large symmetrical lines for blackboard demonstrations. Refer to pages 9-10 of the book 'Leonard Evetts, Master Designer'.
