Nasty cuts on two fingers of my left hand today, after an onion-chopping accident – two layers of the onion unexpectedly detached and slid along each other, one carrying the knife with it.

This is the second time in recent years that this has happened; when the current cuts heal, the scar on my middle finger will sit next to a suspiciously similarly-shaped one on my index finger from 2009. Onions were the culprit on that occasion too.

So perhaps, for my own safety, I should invest in a gimmicky kitchen gadget for chopping onions. A quick google this morning suggests that there are several quite different-looking designs, though, and I'm not at all sure which is likely to be most effective…
