Think of these as the kitchen equivalent of the famous neutral-nation-military-device. ‘Mainichi’ means everyday, which is an accurate estimate of how often you’ll find cause to use them.
Besides the obvious scissor function (aided and abetted by very finely serrated stainless steel blades), they come equipped with a bottle opener, a nutcracker and a lid opener (suitable for the Golden Syrup/paint type of tin).
And when they’re coated in walnut, paint, syrup, bacon etc. you can separate the blades, which makes them easy to clean by hand or in the dishwasher. Oh, and they’re yellow, which will help you find them amidst the chaos of the secondary cutlery drawer.
