The Keyway Ruler
The Keyway Ruler is a comment on the struggle of ‘flipping’ between metric and imperial measurement. The units are kept separate on different faces of the ruler blade to avoid confusion.
The physical movement of ‘flipping’ or ‘rolling’ the ruler between the units has been developed from an investigation into various ruler profiles and features that add to a rulers specific function.
The ‘rolling’ of the ruler allows it to be removed from a page once a line has been drawn, reducing the risk of smudging.
Material choice is dependant on the use of the ruler and therefore could be customised for specific preference. The ruler is available with a brass ‘keyway’ profile which can then be fitted with a steel, walnut or beech blade.
