][1]Selfridges are about to start selling an item called the OCD Chopping Board which is billed as ‘the ultimate kitchen aid for the obsessive compulsive food lover’.
A 9×12″ cutting board made of beechwood, the board is covered in scales, grid lines of multiple sizes and even a printed protractor and marked angles so that you can cut your carrots to a very uniform size.
Didn’t the Romans have something similar just before their civilisation went belly up?
