At our local Sainsbury's the guy who returns the parked trolleys to the

never been tempted to try the technique, partly due to never having
found a need to carry such a knife in public and partly due to the
quantity of fellow shoppers and CCTVs.

They make special tools to do that, are you sure its a knife?

Yup. Standard eating knife. I even asked him and he laughed. Maybe the
ones here are worn - the trolleys are quite old.
