OCD Chef cutting board is terrific for perfectionists as the the beechwood board offers the most precise measurements in detail. You can wash it twenty times after you use it too, if you like.
The board is etched with scales, grid lines and even comes with a printed protractor and marked angles. This supposedly serves to help OCD chefs to perfect their chopping skills. Created by U.S. manufacturer Fred & Friends, the guides show where to slice for 'medium dice', 'small dice', 'julienne' and 'fine julienne' pieces. Sounds stressful!
