A safety razor blade unit has two or more blades (19, 20, 21) with parallel cutting edges (24, 25, 26) mounted in a frame (10) between guard and cap surfaces so that the average inter-blade span is not greater than 1.25 mm, and the wash through index, a measure of the rinsability obtained by a method defined in the specification, is not less than 0.20. The combination of narrow inter-blade spans and good rinsability is stated to enable enhanced comfort levels during shaving to be achieved.
