Here for sale is a rare item from around the early 1970s. This braille ruler was used by my late father, who used it for carpentry work. It’s made from high quality stainless steel, and features both inches and centimetres. The braille divisions are raised dots in inches, and the centimetres are marked in 5cm divisions. Along the edge, inches are sub divided into 1/18 notches, and centimetres are divided by 5 millimetres. Postage is free.
