Google disagrees!
Just seen ep2 of James Mays new cooking show (on Amazon if anyone wants to see it) and he is using a little...thingy to cut herbs that looks like a bit like a wireless mouse but with a couple of round blades poking out of the bottom. You just roll it back and forth over the herbs, NOT one of those two handled things that dont work very well because as soon as the blade dulls, they are an arse to sharpen!
My father would LOVE one but does it have a particular name so I can find a good quality one? Anyone know?!
